"Kids React to... Websites!
This episode: TV Tropes!"

React is Exactly What It Says on the TinThe Fine Brothers, Benny and Rafi, show viral videos, popular songs, YouTube stars, video games, technology and more to various people of either different age groups or Internet fame. As shown by the numerous tropes on this page, this metaseries is easily their best-known creation.

React first debuted as Kids React, where children from 4 to 14 years old react to various videos. This series, which debuted on October 16, 2010, won a special Daytime Emmy Award in 2012 for "Best Viral Video Series" and it was no slouch in winning this either, considering that the series went up against the likes of Epic Meal Time, CollegeHumor's Jake and Amir... and "Can't Hug Every Cat".

When teenage kids enter high school, they "graduate" to Teens React, the second age group in the React series which debuted November 17, 2011 and is based around a similar principle, just with teenagers ages 14 to 19. (After they graduate from high school, they remain on Teens React until they turn 20.) Since those two were made, another React series debuted on May 24, 2012 called Elders React, which obviously has elderly people in the main roles.

The React series came full circle when YouTubers React debuted on December 6, 2012. During the Summer of 2015, the Fine Brothers announced that they would finally be creating a full-fledged Adults React, which would be comprised of parents and college-aged young adults. Adults React premiered on July 16, 2015. In early 2014, they revealed that a television spin-off, called React to That, would be coming to Nickelodeon. It premiered on Monday, December 15, 2014, with 12 episodes having been produced, though Nick ordered 13. They aired daily at 6 PM Eastern until New Year's Day 2015. React to That is formatted differently from the web series: while it features Reactors and celebrities watching numerous viral videos, they also take part in various challenges related to those videos. In a September 2015 episode of Fine Time, Benny Fine said that the chances of a second season of React to That aren't looking great. On August 14, 2014, a React special called "Celebrities React to Viral Videos" was released, which obviously featured more mainstream, non-Internet celebrities.

On January 27th, 2016, the Fine Brothers released an announcement of a new project called React World that was intended to license the React brand to other creators that want to do react videos in the same vein as the brothers. However, this announcement was met with extreme backlash, with many people in outrage over what seemed like an attempt to claim profits over a whole genre of YouTube videos that they didn't even make. Although the channel suffered for quite a while, things seem to have gone back to normal, since they ultimately issued an apology and have cancelled plans for "React World".

All main React episodes can be found on Fine Brothers Entertainment's YouTube channel here. There is also a React YouTube channel as the current home for Kids, Teens, and Elders React's bonus videos, as well as special series featuring the reactors from those shows, over here.

Right now, the current alternating schedule for the series is Teens React or YouTubers React on Sundays, and Kids React, Elders React, or Adults React on Thursdays.

So what examples of tropes have been used in the React shows?

    open/close all folders 

  • Absentee Actor: Despite that they rotate the people around, there are a few regulars and fan favorites missing every now and then. Lia not appearing in "Teens React to Jacksfilms" and "Teens React to Dumb Ways to Die" are standout examples. Seth was gone for five episodes before coming back by popular demand.
    • Interestingly, Benny and Rafi were absent from videos released after the React World debacle.
  • Actually Pretty Funny:
  • Aerith and Bob:
    • Kids has such names as Morgan, Emma, Athena, Samira and Brooke-Monae.
    • Elders has Diane, Don, Rock and Bill, versus Hoagie and Yehuda.
  • Ambiguously Brown: Dylan and Emma R. from Kids, Britney and Brianna from Teens and some others.
    Dylan: "Everyone thinks I'm Japanese, I'M NOT JAPANESE! (I'm) Indonesian! Now you know!"
  • And Now For Something Completely Different: "Teens React to Slender" where in the then-longest React episode ever, rather than having the teens watch to an online video and responding afterwards, they are forced to play a scary computer game with stage lights dimmed, headphones on, and their reactions while playing are captured in real-time. (They still react afterwards, though.) In a much later episode, they got to play Happy Wheels.
    • The elders do the same in "Elders React to Flappy Bird".
    • During "Kids React to Rotary Phones", instead of watching a video, the kids attempted to use rotary phones and discussed the progression of technology. Same thing with "Kids React to Walkmans".
    • The React: Gaming episode focusing on the original Super Smash Bros. on Nintendo 64 is also the very first time ever that non-related reactors are actually seen together in the same shot.
    • The React: Gaming episode focusing on Until Dawn has three different age groups of players playing the game—a pair of Parents, a group of three Young Adults, and a group of three Teens.
  • April Fools' Day: 2014's "Cats React to Viral Videos". The video started with kittens on the Kids React set, then moved on to adult cats on the Teens React set, then finally "CatTubers React", which had some YouTubers React regulars appearing in cat costumes and makeup.
  • Audience Participation: Almost every single topic is suggested by fans, although some viewers have negatively commented on the overwhelming preference for more recent topics. Some of the regulars on the React shows have even questioned why did viewers pick some of the videos they've watched, and have made pleas to the fans to pick something better than what they've put up with.
  • Awesomeness by Analysis:
  • Bald of Awesome: Some of the elders, of course. Victor and Isaac from Teens have a perma-head-stubble thing going for them.
  • Big Ol' Eyebrows:
    • Tom from Teens.
    • Elle from Kids (yes, on a girl!)
  • Bilingual Bonus: Maksim (not the piano player) says goodbye in his native Russian at the end of "Dragon Baby" as well as something a bit longer at the end of "Kids React to The Hobbit". Olga Kay does the same thing at the end of "YouTubers React to Vines".
  • Black Comedy:
  • Blah Blah Blah: From one teen on Shane Dawson to one elder on Barack Obama of all things.
  • Borrowed Catchphrase:
  • Brief Accent Imitation: Every now and then with the kids and teens. In particular, the girls seem to get theirs from Charlieissocoollike, and all the kids do a Southern drawl disturbingly well during "Kids React to Here Comes Honey Boo Boo".
  • Brutal Honesty: Depending on the subject. It's even gotten its own overlay in some episodes; HARSH but TRUTH.
  • By "No", I Mean "Yes":
    • Shane Dawson having been asked if he did any "Gangnam Style" parodies.
      Shane Dawson: I've never done it... only three times... on all three of my channels.
    • Teens veteran Rachel on the subject of marijuana:
      "I've done it once a month, when I can't sleep... Twice a month tops, but I'm not a stoner... That said, my birthday is on 4/20."
  • Call Back:
    • Sometimes done with recycled footage, like one case involving Morgan dancing in the studio.
    • Adam making up a story about picking up girls with dubstep ("Teens React to Jacksfilms") earns him the PLAYA overlay a second time, but with an added FAIL.
    • Ian Hecox and Anthony Padilla mention Dylan's infamous "sushi with [his] blood on it" comment from "Kids React to Smosh", which they were memorably disgusted by when they reacted to that episode.
    • Tobuscus and PewDiePie get featured again in gameplay-footage format in "Teens React to Slender".
    • Invoked in "Kids React to Schmoyoho" when Benny asks the kids which past video in the series they'd want to get the Autotune treatment.
    • You couldn't tell without watching the overlays, but Sam and Niko of Corridor Digital appear in "YouTubers React to Boxxy", which came right after "Kids React to Corridor Digital".
    • "Teens React to Epic Rap Battles of History" could be considered one to "Thrift Shop", from the sheer amount of Squee! from the bulk of the teens to Ethan admitting that white rappers are growing as a thing.
    • During the bonus clips from "YouTubers React to Coffeeshop Viral Prank", MysteryGuitarMan brings up the Scary Elevator Prank covered on Elders React a while back. (And the man himself originates from the same country!)
    • It took about half a month for Steve Cardynal to go from subject ("Teens React to Wrecking Ball Chatroulette edition") to participant ("YouTubers React to News Bloopers").
    • Ethan James was immediately fixated with Attack on Titan once he saw what it was for himself, much like Lia with Doctor Who.
    • Crosses with Passing the Torch in "Kids React to Hello Kitty", when Emma R officially inherits the "Emma's Words of Wisdom" overlay from Emma Johnson!
    • We now have "Elders React to Epic Rap Battles of History" some time after the teens had one, down to a similar reaction to the "step in my shower" line.
    • "YouTubers React to The Slap" has the most targets-turned-guests to date, with first-timers Olajide "JJ" Olatunji (KSIolajidebt), Amazingphil and danisnotonfire alongside Jesse and Jeana of PrankVsPrank and Jon Cozart of "After Ever After" fame, all featured before on Teens.
    • Gaming with Teens can sometimes bring back the subjects of the previous Let's Play episodes, like Happy Wheels or [[{{Video game/Slender}} Slender The Eight Pages]].
    • The episode of Lyric Breakdown where the teens interpret Nirvana's Smells Like Teen Spirit is one to the Teens React episode to Nirvana. In fact, Labib mentions he was in that episode when he found out what song it was.
    • They did the Try Not To Laugh challenge again. Complete with returning contenders!
    • There's a threefold version in "YouTubers React to Don't Hug Me I'm Scared 2 (Time)" - not only does it come after the YouTubers reacting to the original, but the Fines bring up the fact that the kids also had their own session with it.
    • After Josh had to be muted to avoid spoilering Attack on Titan, "Teens React to Mockingjay pt 1" turns it into an Overly Long Gag due to the number of teens aware of that franchise by now. The whole thing actually started with "Teens React to Catching Fire", when Jade gave out numerous spoilers to the film. She even lampshades that she was spoiling.
    • "YouTubers React to Darude - Sandstorm" has Tom Syndicate saying it's "way better than the tentacle porn one", which is most certainly "DyE - Fantasy".
      • Speaking of which, the one with "ME!ME!ME!" also reminded the YouTubers of "Fantasy".
    • The first episode of React to That reuses Marquese's "Pumped Up Kicks" video from early in Kids React!
  • Catchphrase: Lia's "creeper" and Morgan's "Follow me, camera!" There's also Eric's "Swag".
    • Lia did stop using "creeper" after, of all things, "Kids React to Minecraft", but she finally said it again in the Teens and Elders React crossover episode, "Teens/Elders React to Election 2012".
    • Invoked one time with Morgan (ignoring her no-longer-used, "Follow me, camera!" catchphrase). She yells out "Pig supreme!" when reacting to the Rebecca Black video ("It was like "pig supreme". It's a dessert with a pig on top"), which would fit all the requirements of a catchphrase apart from her using it only one other time. (In the same filming session, but shown in a different video, she shouts, "Very fantastic. Pig Supreme," when reacting to Talking Twin Babies.)
    • In Elders React, Richard's "Kind of leaves you speechless, doesn't it."
  • Cloudcuckoolander: Morgan, every now and then. Justified since she's five years old at the beginning of the series. In recent days she's been growing out of that, or at least she's better at expressing it... along with some Hidden Depths.
    • Dylan also started out as being a bit of this, but then later he started showing his own hidden depths... and started wearing glasses.
    • Royel and Emma R. are often this as well, and they're both about the same age at nine years old. Sadly Emma's been growing out of it, but Maksim (who's ten now!) is a serious contender.
    Maksim: "I wish my parents were witches and wizards, then I can do everything I want."
    Maksim: "Does that mean they're a gate? Or the Golden Gay Bridge?"
    Maksim: "If I got a box of microscopes, would I be gay?" (After being explained that "gay" used to mean "happy")
    Maksim(Explaining the problems of some states not recognizing same-sex marriage): "Some people wanna live in one state, and... and they wanna get married... and they just move to the other state, but I'm afraid there's tornadoes... I don't wanna go there, but I have to, because I wanna marry someone I like, that's not right."
    • Some of the elders are this when they get into things, especially Diane. Newcomer Laura can seem a bit... out of touch at times, then in "Elders React to Grand Theft Auto" she suddenly expressed a (disturbing) interest in illegal activity. Oooookay.
  • Color-Coded Characters: The shows' thumbnails on YouTube; a yellow background for Kids, cyan for Teens, grey for Elders and fittingly, red for YouTubers.note  This one's actually consistent across all Fine Bros' works (blue for Spoilers, pink for Last Moments of Relationships, black for Emo Dad and purple for MyMusic.)
    • The React channel takes this a little further, with the Gaming videos getting a pixelated version of whichever background that group (Kids, Teens and Elders) normally gets, and Kids vs Food has the usual yellow back but with a brick pattern. Opinions throws in a new green one, but Advice has the same purple one as My Music despite changing the pattern.
  • Comedic Sociopathy: "Elders React to the Scary Elevator Prank". Thanks to the trick being revealed early, the bulk of the reactions was basically the elders laughing their heads off at the poor victims.
    • Of course, there are other instances of these reactions on the other React series, such as the YouTubers laughing at the German man jumping and falling on the frozen pool.
    • All over the place in "Elders React to Men Giving Birth". Yes, even from the males.
    • Also in "Kids React to Scott Sterling". It's staged, but still.
  • Comically Missing the Point: You expect one of the elders (Vera) to miss that every video is available online, but one of the teens (Jeannie)?
    • Don apparently missed the whole "satire" thing with The Lonely Island.
    • In one Kids React video, Jake figures out that the Fine Brothers are actually brothers.
    • Two of the YouTubers dig instead at the vertical video during "YouTubers React to Viral Gift Videos".
    • In "Elders React to The Interview", Hanoch points out that the Russian tank in the movie is actually American.
    • In "Teens vs. Food: Guess That Pizza Challenge", despite being told that they'll be trying different delivery franchise pizzas, Jayka guesses Chuck E. Cheese (which doesn't deliver) for one slice, Alberto says DiGiorno, then later he and Kaelyn both say Costco, both of which are nationally grocery store bought brands. The DiGiorno is particularly facepalm-worthy, given that their motto is "It's not delivery, it's DiGiorno".
  • Corpsing:
  • Creepy Child: 6-year old Royel sometimes says some unnervingly morbid things.
    (on caviar) "It tastes like eating another thing's dead body!"
  • Crossover: When the kids encounter Epic Meal Time.
    • There is also the first (and so far, only) cross-generational React episode in "Teens/Elders React to Election 2012". Kids React had a separate, individual episode, though their reactions were mentioned to both the teens and the elders.
    • William and Dylan in "Jedi A-holes Strike Back" by Freddie Wong, who returns the favor by appearing in YouTubers React episode 2.
  • Deadpan Snarker: Plenty of the older kids fall into this, mostly Jake and William. Out of the teens, Rumor, Tom, Adam, Alix, and most definitely Eric have their moments. YouTubers React takes this Up to Eleven of course, and the elders are naturally in a class of their own.
    Benny Fine: "Do you want to get married one day?"
    Adam: "Yes. (Beat) I couldn't think of anything smartass to say."
  • Disney Owns This Trope: The announcement that the Fine Brothers would trademark and license "React" series did not go over well on the Internet.
  • Don't Try This at Home: The Fine Brothers put up this warning for "Kids React to Cinnamon Challenge", "Elders React to Challenges (Cinnamon, Salt & Ice, and Milk Chug)", and "YouTubers React to Knife Game Song", and for good reason, too.
    Jake Short: "All of the stuff in this video was attempted by non-professionals, so don't try this at home. Try it at your friend's house."
    • With "Elders React To Eyeball Licking", the Fine Brothers didn't out and out say this as they did with the other ones, but they did show all the health risks it involves, plus the phrase "if you don't want any of the 650+ diseases you can get from this, don't do it", and also highlighted the elders pointing out how stupid the idea is.
  • Dirty Old Man: Not really, but a few of the male elders had no particular qualms in commenting on the attractiveness of certain young females in the videos.
    • Boy, were the YouTubers disturbed when Benny mentioned that Magibon's most popular demographic were men 45 and older.
  • Dramatically Missing the Point:
    • In "Kids React to Controversial Cheerios Commercial", none of the kids knew what the internet uproar was about until Benny explicity pointed it out.
    • Mike "Husky" Lamond in "YouTubers React to Look Up" is so pro-technology compared to everyone else in the episode (even those who were also pro-tech), and so oblivious to the message of not using your personal devices so much and to communicate more without them, that the shown video's idea of selling one's computer for a ring appalls him. To be specific, he doesn't like the idea that someone would get rid of a computer to get for someone else what is normally considered in Western society as a symbol of engagement or marriage, because a ring "does absolutely nothing for you unless it's a magical ring and a computer does everything for you and it's not magical".
  • Eagleland/Testosterone Poisoning: The "BAD ASS" overlay involves camo patterns, warpaint, bullet holes, a bandolier with throwing knives and to top it off, a bald eagle carrying a machine gun.
    • Invoked (with the latter trope) during "Teens React to FPS Russia", of course.
    Adam: "It's too awesome for words, maybe short grunt noises like UUHHH!! UURRRHH!!1"
  • Epic Fail:
    • Spoken by Royel of all kids when reacting to a One Direction music video.
    • Whenever Chelsea plays video games, it tends to end badly.
    • The second "Try To Watch This Without Laughing Or Grinning" challenge. Laina aka the Overly Attached Girlfriend lasts about five seconds.
  • Expy: Emma R. is a lot like Morgan back when the latter was 5. Amusingly, Morgan after her long break is now capable of deep insights just as Emma Johnson was known for.
    • There are some differences between what they like and dislike though; Morgan loved the PonPonPon music video, while Emma R. was just screaming in horror.
    • Bryson could also be seen as an Expy of the long-absent William (though he joined the kids well before William actually left).
      • Interestingly, William's snark and savvy seems to be separated between Eric and Adam from Teens.
    • Royel to Buckwheat unintentionally.
    • Suspiciously Similar Substitute: Derek, who joins Kids just after Bryson graduated to Teens.
      • Rae in "Teens React to Attack on Titan" is pretty much an Asian Lia (who's moved on to YouTubers instead).
      • Claudia in Kids takes the Valley Girl reins from Paris, who's been absent for a while.
  • Eye Take: Morgan during the "le Internet Medley" video. She was laughing, and suddenly went "O_O what the heck?!" when the ALL YOUR BASE ARE BELONG TO US part barges in.
    • Some of the teens watching the honey badger tear up the snake.
    • Isaac during Teens React to FPS Russia.
  • Facepalm: Done occasionally. Also in headdesk variant!
  • Fanboy:
  • Fingerless Gloves: Mikaela in "Kids React to Golden Eagle Snatches Kid" for some reason.
    • Jeannie in "Teens React to Psy—'Gentleman'".
    • Britney is rocking this one-sided fishnet affair in "Teens React to Hair Tutorial Gone Wrong".
  • Flat "What.": When Ethan was told that some people think Nicki Minaj's song Anaconda was feminist.
  • Follow the Leader: There was an attempt at a British version of Kids React by a group not related to the Fine Brothers.
    • There was also a "Seniors React to LMFAO" (specifically the "Sexy and I Know It" video), inspired by Kids React while inadvertently predicting Elders React.
    • Some personalities have made "X Reacts to Kids/Teens/Elders React to X" videos in response to being featured on the show. This includes Smosh, KSIOlajidebt, and PewDiePie.
    • The Fine Bros are guilty of this. What do you call a Let's Play when they do it? "{Group} reacts to {Video Game}.
  • Freeze-Frame Bonus: Invoked in this special announcement, where the newest additions to YouTubers React were subtly revealed in this fashion. Grace Helbig was revealed this way.
  • Funny Afro: Royel wore one like a boss, but sadly he turned it into dreads in "Kids React to Luigi Death Stare".
    • Ethan's been deliberately growing one, even leaving his afro pick in it sometimes... until he trimmed it right off by "Teens React to The Fox". Sigh.
  • Fun T-Shirt: Several from the teens, YouTubers and even elders. Of special note, Alix has a The Legend of Zelda one, and newcomer Richard from Elders has this 'Irish Yoga' one.
  • Gender-Blender Name: The black chick on Teens is named Kennedy, and a blonde girl in Kids is named Cooper.
  • Genki Girl: Justine Ezarik can not sit still.
    • Rae from Teens is probably more hyper than half of the kids put together.
  • Genre Blind: In spite of the many examples of Genre Savvy throughout all the shows, a few examples crop up every now and then.
    • Literally none of the YouTubers expected that they would be the victims of a Rickroll. When the Fine Brothers offered to show them some news footage related to it, literally only three people worked out it was going to happen again, and of those three two of them were a double act. Lampshaded by Jack Douglass, who commented "Should have seen that coming!"
  • Genre Savvy: There are many examples, and generally anyone who's on the show becomes this if they aren't already.
    • Yehuda is the first one to be suspicious of the mirrors in the elevator. Rock apparently anticipated the direction the video would take when the first male victim appeared.
    • Quite a few guys predicted the screaming goat in YouTubers React #6. Similarly, Smosh even mentions Rule of Three for the Knife Game one.
    • Kurt Schneider was the only person to predict that Don't Hug Me, I'm Scared was going to suddenly get disturbing, even timing his guess as to when it was going to happen and getting it exactly right.
    • This gem from "Teens React to The Fox":
    Tom: "It's funny, 'cause I just seen these guys on Ellen, the talk show and... I knew that was one of your questions I just knew it!"
    • "YouTubers React to the Farting Preacher". Phillip DeFranco was the first to assume Pastor Tilton met some kind of Laser-Guided Karma eventually, as well as predicting the "fart version" of the whole episode whether they consented or not.
    • Yehuda returns for "Elders React to Oculus Rift", and is the first to predict a rollercoaster!
    • Similarly, Adande predicts the Fines bringing out an actual rope in "YouTubers React to Ylvis - Trucker's Hitch".
    • Labib eventually figures out that Sonic.exe was a Creepypasta game. His first guess wasn't too far off (He said it was some Illuminati game).
    • In the Elders Play The Last of Us, both Catherine and Anne know right away from the dialogue that the soldier is going to kill Joel and Sarah.
    • In Elders Play Grand Theft Auto V Catherine gets a nice quip in;
      Catherine: "That's his wife or his girlfriend? [Amanda drinks a cocktail.] Who's an alcoholic?"
      Amanda: "Six more of these and I'll be comatose enough to sleep with you."
      Catherine: "It's his wife."
  • Gone Horribly Wrong: The huge backlash against their announcement that they would trademark and license "React" series resulted in them losing a chunk of their subscribers. They later apologized and dropped the plans altogether but the damage had already been done.
  • Gosh Darn It to Heck!: Troy, misunderstanding the lyrics of Psy's "Gentleman" ("I�m a, mother-father-gentleman")
    Troy: "I'm a... mother-truckin' something."
  • Graduate from the Story: From Kids React (at age 14, upon entering high school) and then from Teens React (upon reaching age 19, then later extended to 20, after graduating from high school). From there, it's on to Adults React for those from 20-55, then Elders React for those who are 55 and up.
    • Lia pioneered the graduation from Kids to Teens. Bryson, Claudia, Darius, Derek, Dylan, Elle, Everhet, Jayka, Lydon, Megan & Shannon, Mikaela, Olivia, Riley, Seth, Sydney, Thomas and Troy have since followed in her footsteps.
      • Lia skipped the Teens age limit and, starting with "YouTubers React to News Bloopers 2013" at the age of 17, became the first person to go from Kids to Teens to YouTubers.
    • Lucas Cruikshank is an odd celebrity example. He was 18 when he made a one-off guest spot on Teens React. The next time he's seen on a React series, he's 20 and appearing on YouTubers React with Jennifer Veal.
    • Ethan James, Jeannie and Madison were the first Teens React alumni to jump to Adults React. Since then, they have been joined by Adam, Alix, Brianna, Brooklin, Jasser, Jourdan (now with his twin brother Jeremy), Kennedy, Kostas, Labib, Morgan, Rachel, Sam, Shant, Sophia and Tom.
    • Special mention goes to Jade, who was the first teen to formally graduate from Teens React, but did so before the creation of Adults React.
  • Hair Decorations: Morgan, in her Christmas costume.
    • Rumor in "Prank vs Prank" has a Union Jack bow that matches her blouse!
    • Cooper and her hippy headband. It's not an easy look to pull off.
    • Newcomer Chloe from Kids always has one on her already prominent 'do. Always.
  • Hair of Gold, Heart of Gold: Lia is definitely one of the nicer people in the series.
  • Head Desk: When Adam finds out that a large number of teenage boys and grown men like My Little Pony.
  • Hidden Depths:
    • As mentioned above, Morgan and Dylan from Kids.
      • Emma R may have raised a few gamer eyebrows when she somehow 'got' the concept of level editors (re. Super Meat Boy).
      "I got a question - Are all these levels makeable?"
    • Adam, Rumor and Jade from Teens. The girls in particular may seem like unabashed Valley Girls, but Rumor can rattle off all the character names in Mean Girls, while Jade can name every Jennifer Lawrence role, which is not easy.
  • Huge Schoolgirl: Mikaela's always looked somewhat out of place during her time on Kids React for this reason. During the Gaming with Teens head-to-head session, she's actually taller than Josh, who should be older than her.
  • Hypocritical Humor: Jayka issuing death threats in "Kids React to Harlem Shake" when she was the one laughing the hardest.
    • Steve Kardynal remarking on the audacity of photobombers in "YouTubers React to News Bloopers". This is a guy known for swinging naked on a yoga ball, folks.
  • Identical Twin ID Tag: Megan and Shannon just part their hair differently, though in "Kids React to Election 2012" they have identical hair but different colored outfits. After they moved to Teens React, Shannon started wearing glasses on occasion.
    • There's also Kelli and Alisyn from the Adults side (yes, adults) who are virtually identical from the neck up.
  • Idiosyncratic Episode Naming: "[Age group or YouTubers] React to [Topic]"
  • Innocently Insensitive: It's Lia, so it may well count as this:
    Benny Fine: "Which specific ex-boyfriend do you think "We are Never Ever Ever Getting Back Together" was about?"
    Lia: "Oh my god, I can't name them all!"
    • And during the exclusive "Kids React to Vidcon":
    Benny Fine: "What kind of people do you think go to Vidcon?"
    Darius: "People who don't have a job."
    Everhet: "People who have no life and are covered in acne."
    • Dylan going "he's too old to have that kind of girls" in response to One Pound Fish. The guy's only 31!
    • However, Dylan scores some points for knowing what Harlem is ("Kids React to the Harlem Shake"), while Everhet thought it was "a prison or a very bad neighborhood".
    • Jeannie from Teens has been afflicted with foot-in-mouth disease for quite a while now.
    "He's like a... nice child molester?"
    • Claudia may have earned a medal for this by now - first off, in the one with a film-using camera:
    Benny: "So it used to be, you had no idea how the pictures turned out, until you brought them to a store... and waited one hour for the film to be developed..."
    Claudia: "I feel bad for those people."
    Rafi: "...Us."
    Claudia: "Oh, I'm sorry."
    • And in a later ep, when Benny says Power Rangers has been around for more than 20 years and that he and Rafi watched it when they were kids.
    Claudia: I didn't realize it was that old. I thought...
    Claudia: *while laughing* I'm sorry!
  • It's the Best Whatever, Ever!: Darius on Schmoyoho.
  • I Want You to Meet an Old Friend of Mine: Bordering on the literal interpretation of this trope, the Teens React episode released on December 17, 2012 features Jacksfilms by Jack Douglass, who already has a role (Intern 2) on the other major Fine Brothers' production, MyMusic.
    • Then crosses that border in YouTubers React episode 3, with Grace Helbig (Idol) actually in the studio! Then comes Jack himself in episode 5!
    • Strangely inverted with "Teens React to Tyler Oakley", who's appeared on YouTubers React enough times to be considered a regular. There's also "Kids React to Miranda Sings", created by Colleen Ballinger, who'd been absent from YouTubers React right until the following week.
  • Jaw Drop: Kostas in "Teens React to Facebook Parenting".
    • A beautiful one from Don in "Elders React to Happy Tree Friends".
    • Paris and Morgan in "Golden Eagle Snatches Kid".
    • A perfect one from Lia when she finds out who originally did the cup song in "Teens React to the Cup Song".
    • Diane while watching the Jersey Shore cast get violent.
    • Royel in "Kids React to Going To The Store". And then he resets it manually.
    • Barbara in "Elders React to A Million Ways to Die in the West".
  • Loads and Loads of People: There are quite more than a few regulars that get rotated around often in each React series. Usually, these recurring people may be absent so that the Fine Bros can balance each episode between regulars, newcomers, and the occasional Special Guest.
  • Medium Awareness: "HEY! YouTube videos AREN'T crappy."
    • The teens also became aware of the overlays as well, like the red X's and green check mark for the rapid-fire Q&A.
    • This golden moment in "YouTubers React to Rewind YouTube Style":
    MysteryGuitarMan: "I think it's a brilliant thing to get a bunch of YouTube stars to be in one specif- Wait a second! WAIT A SECOND! I know what this is! I know - you guys are using me!" (leaves in a mock hissy fit)
    • "YouTubers React to the Farting Preacher". Half of the guests actually sensed that the fart sounds were being added to the episode "right now" rather than in post-production.
    • A rare one from one of the kids in "Kids React to ALS Ice Bucket Challenge".
    Emma R: And now of course it's, QUESTION TIME! (beat as we hear the Fines laughing) I've been here long enough to know everything!
    • Barbara has always proven rather Genre Savvy, until this moment in "Elders React to First Moon Party":
    "I was in school, and I was like "I got it mom!", "Well come here, let's take care of it!" (beat) Oh gosh this is going on the internet..."
  • Megane/Meganekko: Morgan from Kids React on occasion (though she doesn't actually need glasses).
    • Many of the Teens, such as Alix, Anna, Britney, Brooklin, Carlos, Daniel, Ethan, Jade, Jeannie, Jeordy, Leyla, Makena, Mikaela, Nora, Olivia, Rachel, Rebecca, Rumor, Sergio, Seth, Troy, and Will have all worn glasses on at least one occasion, though Alix, Makena, and Sergio seem to be the only ones to wear glasses on a regular basis.
  • Mood Whiplash: What follows "Teens React to Bullying (Amanda Todd)"? "Kids React to 'It's Thanksgiving' (Nicole Westbrook)".
    • Near the end of the latter episode, Morgan went from being calm and polite to mad and argumentative upon hearing that a lot of people dislike the song just for the heck of it. Note that Morgan was one of only a couple kids who likes this song and was very defensive of it.
    Benny Fine: So many people are so mean about this video, but you're so nice about it.
    Morgan: Thank you.
    Rafi Fine: So many people seem to find it fun to not like videos.
    Morgan: That is bad! Bad! Just don't even give it thumbs down, just say you hate it, but don't show it!
    • There's several cases of conflicting views lined up together.
    • "Elders React to 50 Shades of Grey Trailer" drops a MASSIVE one at the end, abruptly cutting to black immediately after giving one of the elderly women the "PLAYA!" overlay, and solemnly dedicating the video to one of the elders who had passed away that week.
  • Mundane Made Awesome:
    • YouTubersReact has the most dramatic background music, as if the Fine Bros are trying to tell us that watching YouTubers watching and reacting to other YouTube videos is awesome.
    • Teens React to 90s Handheld Games. Clearing a round of Bo Jackson Football leads to a couple of touchdown celebrations.
  • Mythology Gag: Dash regarding one cat video as "quality internet video", referencing the Fine bros' "Spoilers" series.
  • Nice Hat: Some kids and teens on random occasions. Jake's fedora is a notable Kids React example.
    • Rock from Elders wore his stetson into the studio for "Election 2012" and (quite appropriately) "Gangnam Style".
    • Yehuda Fine wears his black baseball cap backwards.
    • Jeordy's feathered hat in "Teens React to the Cup Song"
  • Noodle Incident:
    Maksim: "Once I bited one of my parents, and he had blood."
    • From "Elders React to Murdered My Wisdom Teeth":
    Rock: "I had a back operation... when I came out, I was really in a different place, and I thought I was in Vietnam."
    • In "Teens React to Wrecking Ball (Chatroulette Version)", the teens are asked how they'd react if someone like Steve Kardynal appeared on their screen.
    Madison: "I'd close my computer and be like, 'Ah! No! Not again!'"
  • Not So Different:
    • "Elders React to Elvis Presley". The elders can Squee! just as much as the teens, you just watch.
      • The elders regarded Elvis Presley's weight gain and evolving into his Vegas image in the same vein as the teens did to Miley Cyrus and her derailment.
    • "YouTubers React to Japanese Commercials #2" scores a new first by getting actual Japanese folks to watch them as well. It's no secret that Japanese commercials are outlandish and ridiculous, but one of the Japanese YouTubers points out that there's Western commercials like that - the Terry Crews Old Spice commercials.
  • N-Word Privileges: From Ethan laughing off the idea that he would still be a slave if not for progress and amendments, to Royel just blurting out "is he black?" in response to the One Pound Fish guy (Pakistani, for the record).
  • Once per Episode: Question Time!note 
  • One of Us: Several kids on the show, especially William. Also invoked with the teens, and seems to be the whole point of YouTubers React.
  • One Steve Limit: Averted. They've managed to have two Emmas, both of whom stand out on their own merit ("Emma's Words of Wisdom" and Emma R. just being herself).
    • After the guest appearance of Alex Steele ("Teens React to the Honey Badger"), they've managed to get a male Alex for their next guest. ("Teens React to Jacksfilms")
      • We've also had two Lucases (one guest on Teens, one regular on Kids). And it took a while but they now have a second Morgan, who's alongside Morgan Bertsch (the regular) in "Kids React to Grumpy Cat".
    • They've even got two Adams; the Teens React regular and Tay Zonday, whose real first name is Adam. Similarly, we now have a Lloyd in Elders after EpicLloyd from Epic Rap Battles of History went on YouTubers.
    • "Kids React to Old Computers" introduces a second Sydney, except they forgot to initial her last name like they've done before.
    • And now we have a third Morgan on Teens, setting a new record.
  • Precision F-Strike:
    • Emma R getting "a little pissed off" at Mario Vs Minecraft's ending.
    • Alix from Teens React delivers a contemptible "God dammit" when she's forced to play Slender.
    • Several from the Amanda Todd one, and not without reason.
    • "He's on the floor singing and that guy was dryhumping his face!" Not only a bit of exaggeration, but the Japanese fansubs had to censor that bit.
    • A beautiful one at the end of "Elders React to Jersey Shore":
    Catherine: "Take a shower, wash your hair, put on some clothes, go out and get a job and leave us the f—k alone."
    • One of the rare meaningful ones from "Teens React to Dumb Ways to Die":
    Kostas: "Big things going really fast are gonna f—k you up, so don't f—k with trains."
    Overlay: "KNOWLEDGE (A public service announcement from Teens React)"
    • We got one from Jordan Maron, aka Captain Sparklez in "YouTubers React to Farting Preacher". Normally, he doesn't use swearwords beyond "crap", or "damn", but upon learning that the farting videos were fake we get this gem.
    Jordan Maron: "I am so fucking gullible!"
  • Product Placement: Friskies sponsored their April Fools' Day 2014 video.
  • Put on a Bus: Some of the React series' old regulars have ended up leaving the show for no apparent reason.
    • The most notorious example was William Sherman of Kids React, arguably the most popular of the kids (even over Lia), whose absence spurred frequent inquiry in the comments section of many Kids React videos and on William's own videos. Eventually, he gave a reason for his departure.
      • Other departed kids include Athena Stamakinley, Emma Johnson and Jake Jacobson.
    • Several of the original teens from Teens React have aged out of the show and departed without fanfare, including Devin, Jourdan, and Kostas.
    • Diane, a mainstay of the earliest Elders React episodes, suddenly stopped appearing and hasn't returned since.
    • The Bus Came Back: There was a long period of time when Morgan was absent from Kids React, but then returned to the series a bit older. She's not on as much again.
  • The Quiet One: Rafi, probably because he's operating the camera. Benny is the one who asks the questions, with Rafi speaking up or laughing along with Benny about a quarter of the time.
  • Rage Quit:
    • A minor version in "Teens React to Happy Wheels", when Rachel goes through three attempts, only to come closer and closer to stopping short of the finish line.
    • Evan's final word on the Skip-It.
  • Reaction Shot: Well, duh.
  • Real Life Writes the Plot: "Teens React to Markiplier" comes after the longest reverse period in which a subject turns Youtubers React guest. It's most likely triggered by Mark's appearance on Jimmy Kimmel Live.
  • Recurring Character: Lia is the only person to have appeared in three of the different series. (She started on Kids React, grew older and joined Teens React, and due to having her own YouTube channel, got featured on YouTubers React.)
  • Recycled Premise: This page covers it fully in detail.
  • Running Gag: A few.
    • Emma's (and later others') Words of Wisdom.
    • "Aw... CUTE!"
    • There were also three or four instances of Words of Zen.
    • TRUTH!
    • PLAYA!
    • A Teens React-specific one has Eric trying to hook up with the pretty women that he has just seen in the videos by giving out his phone number, only to be censored post-production after the 925 area code to protect his full identity.
    • The screen going Deliberately Monochrome and skewing when one of the folks starts getting scary. This one gets cranked Up to Eleven with the addition of an Evil Laugh and a pair of steepled hands a la Gendo Ikari.
    • By "Elders React to A Million Ways to Die in the West", Don going "I'm in love" at the sight of any nubile female is becoming one.
  • Sassy Black Girl: Kennedy from Teens is a mild case. Maiya from Kids is a pretty straight example.
    • Brooke-Monae from Kids falls into this more often than not.
  • Screw This, I'm Outta Here!: A few times, like Shane Dawson mentioned above, and even Maksim in "Kids React to Ariana Grande".
    • Lia finally got Squicked into doing this in "YouTubers React to Little Baby's Ice Cream".
    • Kids vs Food has this gem.
    Benny: How much do you think a jar (of caviar) like this costs?
    Sydney: If you say $10,000 I'm just gonna walk out of this room.
  • Self-Deprecation: From some of the girls on Shit Girls Say.
    Lucas Cruikshank: "I know some girls that are more manly than me!"
    Shannon: "It's called 'American entertainment'."
    Megan: "We are stupid."
    Overlay: TRUTH
    Owen: "I'm a sick f—k, what can I say?!"
    • From "Teens React to the Cup Song"
    Kennedy: "Some of my friends are like, 'I play the cup.' I think it's a "cool" instrument to play. I just play the didgeridoo and the violin"
    • From "YouTubers React to Rewind YouTube Style"
    Ian: "It's just a bunch of random douchebags..."
    Anthony: "Some YouTube stars who "think" they are famous!"
    • This one from "Kids React to Grumpy Cat" when the kids try to come up with funny captions:
    Bryson: "'They canceled Kids React' and make him say 'Good'."
    (The Fine Brothers laugh with Bryson.)
    • From "Teens React to Twilight"
    Fine Brother: "How does it make you feel about society knowing that things like Twilight are things that become so popular?"
    Jeannie: "We suck."
    • Nick Cannon in the first ever Celebs React:
    "Yo, let's get in the studio. You make bad music, I make bad music. This could be amazing... a collaboration... it will go double cardboard."
  • She Cleans Up Nicely: Jeordy from Teens.
    • Catherine from Elders is almost unrecognizable in a pantsuit with her hair up.
    • Alix in "Teens React to Jonah Hill Controversy" is at her least emo yet. Floral top, people!
  • Shout-Out:
  • Small Reference Pools: On average, about a fifth of the people already know of the subject matter. The teens (and YouTubers!) can be counted on to skew this figure up to a third, but not always - just watch what happened when Lia only just learned about Amanda Todd.
    Pamela (reacting to Breaking Dawn Part 2): "I've seen this before on TV... The Vampire Diaries."
    Evan: What if back then, if these things happened and the same thing happened, and George Bush was writing the... Democracy of Independence or something... and out comes a big bucket full of ice water. Aaaaah!
  • Special Guest:
  • Spin-Off: Teens React, Elders React, and YouTubers React are all really this to Kids React. ReactToThat will be a television one for both Kids and Teens.
  • Squee!: Morgan's first reaction to the Nyan Cat.
    "It's heaven... It's heaven on Earth. It's Heaven in July."
    • Nearly all the celebs in response to the Japanese commercial with the Mega Neko.
  • Strange Minds Think Alike: Lampshaded when the Fine Brothers tend to edit all the nearly-identical reactions in direct succession.
    • When the elders were asked about what they'd do to the Creepy Child ("Scary Elevator Prank") and the kids about what they'd do when approached by a stuffed dragon toy ("Dragon Baby"), the phrase "probably kick it" came up both times. Similarly, both Morgan from Kids and Madison from Teens say "put some pants on" in regards to the Harlem Shake.
  • Strictly Formula: We watch a bunch of people of a certain age group (or a bunch of Internet video celebrities) watch a video or a series of videos that are related to the subject of discussion and see their reactions to those videos. Then, two producer brothers ask them questions about what they've just watched. After that, the interviewees say goodbye to us and request that we give a thumbs up to the video we've watched, subscribe to the producers' YouTube channel, and suggest a new topic for them to cover.
    • A few exceptions to the first part include "Teens React to Slender", "Teens React to Happy Wheels", and "Elders React to Flappy Bird", where they played a video game instead. These were popular enough for the Fine Bros to make a new series where they play games on the new React channel. "Kids React to Rotary Phones", "Kids React to Walkman", "Kids React to Old Computers", and "Kids React to Typewriters" had the kids actually interacting with real older technology.
    • The Very Special Episodes often lack the goodbyes and replace the intro with a message from the Fine Brothers explaining why they've decided to have them tackle these stronger subjects.
    • YouTubers React tends to be about two-thirds Internet culture (either YouTubers or memes) and one-third pop culture, up until they switched to a single video per session, which is the same with Kids React originally.
    • The first Celebrities React actually starts with the three-videos format just like Kids and YouTubers did!
  • Stupid Statement Dance Mix: Courtesy of Mike Relm.
    • React Remix on the React channel will be just this.
  • Take a Third Option: Literally in "Teens React to Rick Perry's Strong"; a snap poll is taken and it's a landslide vote against voting for Rick Perry, until Devin goes "I'm more of a Ron Paul kind of guy". This is noted beside the scoreboard.
  • Take That!: With so many different reactions, some fall under this, such as this quote:
    Harley: Let us know in the comments what you think the Fine Brothers should be forcing other YouTubers to watch next.
    • From one Advice on the React channel:
    TJ Loamanu: How do I become a member of 1D?
    Jaxon: It's people like you that are wrong with this world!(sic)
  • Tempting Fate:
    "It's not violent for once." (piano falls on someone in the video) "Oops! I said it too soon."
    • New kid Evan on the ALS Ice Bucket Challenge.
    (after dunking himself) "...oh my gosh... It's not so bad." (gets a second bucket)
    • The Outlast session. Tom gets through the Almost Dead Guy scenario, then starts making his way out to the barricaded corridor, then randomly quips "ever get that feeling somebody's following you? I'm getting that right now." Cue Chris Walker grabbing him and hurling him downstairs.
      • Even better: just minutes before that we had Seth going "I am so tense right now... just (exhales) just relax." Cue the first Jump Scare.
  • Token Mini-Moe:
    • Kids has had Morgan, Emma R. and Cooper. Sydney currently fills this role.
    • Chelsea from Teens, which is notable as she wasn't moved up there from Kids before.
    • If the Elders even qualify, Hoagie actually fills this role.
  • Valley Girl: Paris from Kids. "She is like The Bomb dot com!"
  • Very Special Episode: Recognizable by the message screen before the opening, and the opening itself being more "solemn" (such as the Kids React opening lacking the "children" shouting the title). The Kids React episode for the interracial Cheerios commercial did not even have a title card.
    • Kids React: The ones on KONY 2012, bullying, Osama bin Laden's death, the Cheerios "Just Checking" commercial and same sex proposals were more serious and more thought-provoking than the average episode (especially the KONY 2012 video).
    • Teens React also covered bullying, having been shown the Amanda Todd video on React's one hundredth episode. Weeks later, they've covered the Sandy Hook Elementary School shooting in Newtown, Connecticut. They were also shown the "Jeff Bliss" video, although that wasn't quite as serious as the other two. The teens have also covered the Jonah Hill controversy, which lead to a discussion about homophobic slurs. And on top of that, they have covered the topic of drunk driving.
    • The Memorial Day episode "Elders React to Homeless Transformation" doesn't do anything different with the opening, but is intended as such.
    • Teens React to Drunk Driving
  • The Voice: The brothers never appeared onscreen until Benny appeared in the bonus footage of "Teens React to Prank vs. Prank'' (as well as Rafi's hand). Both of them appeared in a main video for the first time at the end of "Teens React to Harlem Shake". This is because obviously they want the focus on the subjects, not on them. Besides, it doesn't matter much, since they have appeared in the flesh in their other shows well before these videos were made.
    • The Voiceless: More and more often in the React channel productions.
  • Why Did It Have to Be Snakes?:
  • Wrong Genre Savvy: A few examples across all media.
    • In "Kids React to Never Say No to Panda", the children thought the titular series of adverts were from China (owing to there being a massive panda) or Japan (since adverts there are considered more weird and surreal compared to the United States). It was actually Egyptian.
    • In "YouTubers React to Rick Roll", Justine thought that the news report would be some news that Rick Astley had felt somebody up.
    • In "YouTubers React to Viral News Clips", Kurt Schneider, plus a few others, thought that the news clips would be autotuned. This caused them to get so distracted that they were not entirely sure as to what they'd just watched.
    • In both the Kids React and YouTubers React episodes of Don't Hug Me, I'm Scared, the participants mistook it for a British version of Sesame Street. It was far worse, needless to say.
  • Younger Than They Look: Quite a few of the kids and teens. In particular, Mikaela only just joined Teens React, by way of turning fourteen well after Bryson and Seth, both of whom easily look younger than her.
    • Older Than They Look: for one, Jake Short returned to Teens React ("Hair Tutorial Gone Wrong") eight months after he first appeared in "Salad Fingers", and he has not aged a day. Same for newcomer Will, who looks like he's 9 but is actually Fifteen!
      • It's also hard to imagine Ethan James reaching 20 and leaving Teens React well ahead of longtime regulars like Tom, Adam, Rumor and Alix, but that's just how it is.

    Kids React 
  • Adorably Precocious Child: Morgan, hands down.
  • Berserk Button:
  • Big "WHAT?!": Morgan every now and then.
    Anthony Padilla: "Was she doing an impersonation of a parrot?"
  • Blinding Camera Flash: When reacting to an '80s camera, several of the kids discover exactly why selfies didn't become a thing until cell phone cameras were around.
  • Bowdlerisation: While Elders and Teens got to react to "Anaconda" by Nicki Minaj, the Kids instead got "All About that Bass" by Meghan Trainor, a family-friendly take on the same subject.
  • Breakout Kid: Likely due to being older, Lia Marie Johnson was significantly more popular than the other regular kids—which is probably what led to Teens React. She even appeared in the video that announced Teens React, then later made it on to YouTubers React.
    • Morgan Bertsch seemed to be the viewers' new favorite kid on Kids React after Lia moved over to Teens React.
    • William Sherman was also a popular kid on the show, due to him being more aware of what happens on the Internet than any of the other kids, as well as for being a Deadpan Snarker. In the comments section of some post-William Kids React episodes, some fans have stated how much they miss him and even tried asking why was he no longer on the show.
    • Jaxon has gained a cult following on Instagram. He also has a fan made video celebrating his birthday and even a fan-made website!
  • Cat Fight: What Megan and Shannon do when asked if they could do any karate moves.
  • Cheerful Child: Many, many, many kids. And they're all adorable! Aw... CUTE!
    • Special mention goes to Cooper, currently holding the record for youngest child by joining up at the age of 4.
    • Morgan, who wants to teach Honey Boo Boo how to play baseball.
  • Children Are Innocent: Occasionally subverted, but played straight a surprising number of times. For example, one kid commenting on "Don't Hug Me, I'm Scared" (particularly a disturbing part where a cake is cut open to reveal red, raw meat) insisted it was just "peanut butter and jelly," prompting the Aw... CUTE! overlay. Also, none of them understood why anyone would get angry over the Cheerios commercial portraying an interracial family.
  • Computer Equals Monitor: Invoked in "Kids React to Old Computers" - pretty much all the kids found the monitor switch and expected that to start the old rig up. It wasn't quite like that back then.
  • *Cough* Snark *Cough*: Lia, when asked about what does she think about people who do LARP: "*cough* Nerds!"
    • Similarly, Seth on whether the Dragon Baby was real: "*cough*CG*cough*"
  • Cover Innocent Eyes and Ears: In "Kids React to Teddy Ruxpin", each kid is given a Teddy Ruxpin doll. When they are asked why the dolls aren't popular anymore, Morgan A. responds:
    Technology is like, booming and great and so by then we had computers and touch screen phones and all that and nobody really cared about Teddy anymore. (covers Teddy's ears) I hope he didn't hear that.
  • Cute Mute: Royel, when he's not speaking.
  • Cuteness Proximity: Paris is practically Squeeing over the Dragon Baby video.
  • Dark-Skinned Blonde: Emma.
  • Deadpan Snarker: Dash, especially impressive considering he's not even ten years old.
    [When prompted to enter his name in a game] I'm just gonna do DASH, because I have no imagination.
    [When asked whether or not he recommends broccoli, in a completely flat tone] Yes. Look at it. Look how appetizing that looks.
  • Dissimile: On "Kids React to Pumped Up Kicks Dubstep":
    Benny Fine: How would you describe the way he was dancing?
    Emma: Just like Michael Jackson... except Michael Jackson's dead and that really sucks.
  • Elmuh Fudd Syndwome: Emma R.
  • Entendre Failure: The suggestive lyrics from "Live While We're Young" are lost on some of the kids.
    Benny Fine: "'Tonight let's get some/And live while we're young'. Get some of what?"
    Royel: "Pancakes? Chicken McNuggets?"
    Dylan: "Sandwiches?"
  • Failed a Spot Check:
  • Flat "What.": William's reaction to the existence of a six-hour version of Nyan Cat on YouTube.
  • From the Mouths of Babes
  • Fun with Subtitles: Occasionally, or rather especially when Royel is involved.
  • Girls Love Stuffed Animals/Security Blanket: Athena Stamakinley is virtually never seen without Toasty, her stuffed koala, which even appeared at the Emmys wearing a matching dress! That, and she's 14, pretty much ready to move on to Teens React!note 
  • Harmful to Minors: When they compared Ariana Grande to Miley Cyrus, a couple of the kids accidentally outed themselves as having watched Wrecking Ball.
    • Averted in "Kids React to Luigi Death Stare" - the videos use the most commonly used tune, "Ridin'" by Chamillionaire, but only the bridge and not the whole song.
  • Improbable Hairstyle: Olivia's 'do is particularly bouffant for a 12-year-old.
  • I'm Taking Her Home with Me!: Morgan on the Nyan Cat: "Didn't you want to kidnap her, people?"
  • It's Hard, so It Sucks:invoked Within the show, a lot of the kids have this reaction when presented with old technology.
  • Jitter Cam: "Kids React to 10 Bets You Will Always Win", though this was only to get a close-up view of the kids' fingers when they attempted to replicate one of the pranks.
  • Men Don't Cry: When the brothers reveal the they cried at the end of The Return of the King:
    Paris: "Men crying? You guys are kinda... weird."
  • Named After Somebody Famous: Maksim, as mentioned below. Dash is a pretty obvious one.
  • Non-Indicative Name: Sometimes the kids are shown a viral video whose name has nothing to do with its subject matter, such as "Going to the Store", "Late For Meeting", or "Don't Hug Me I'm Scared". The brothers will always ask the kids what they think the title of the video is. Cue incredulous reactions such as "That doesn't make any SENSE!!!" when they are told the actual title.
  • Precocious Crush: Morgan seemed to have one on Benny. Until they told her that Smosh was more popular, anyway.
  • Rapidfire No: Lucas.
  • Retraux: Newcomers Thomas and Derek are rocking a '70s moptop and '90s slicked-back do respectively, something you really wouldn't expect to see in Kids.
  • Sarcasm Mode: Dylan. Frequently.
  • Slow Clap: From Bryson in "Kids React To Fake Celebrity Prank NYC".
  • Space Whale Aesop: From "Kids React to Simon's Cat":
    Bryson: "Remember to feed your cat or he'll hit you with a bat in your sleep."
  • Speak in Unison: Megan and Shannon occasionally do this.
  • Spell My Name with an "S": One of the kids is spelled either Maksim or Maxim. Maksim is also a piano player while Maxim is an adult mag... Oddly enough, new episodes with him use the latter spelling.
  • Tears of Joy: The kids fake them at the end of "Lily's Disneyland Surprise...AGAIN!"
  • Title Scream: "Kids React to [Category]! This episode: [Subject]!"
  • Troubling Unchildlikebehavior: Some of the things that comes out of Royel's mouth is not what you'd expect from a little kid. He also sings along to the "Don't Hug Me, I'm Scared" video.
  • Twin Banter: Megan and Shannon get into this sometimes. They're notable for averting a lot of other Twin Tropes, though, so the banter often comes from them having drastically different opinions on something.
  • The Unintelligible: Royel, when he's speaking. He sometimes has to be subtitled.
    • Same goes to Emma R. at times.
  • Unusual Eyebrows: Lucas. They look like a misplaced mustache.
  • What Are Records?: The kids in Kids React have no idea how to work a rotary phone. Granted, rotary phones have been obsolete for longer than some of the kids have been alive, but it's still interesting to watch their confused reactions.
    • Dylan however is usually remarkably quick to pick up on whatever older tech the Brothers hand him and, unlike the some of the other kids, appreciates how important its impact was.
  • What Were They Selling Again?: In "Kids React to The Epic Split", some of the kids don't even realize that the video they've seen was a commercial.
  • Wise Beyond Their Years: "Kids React to Controversial Cheerios Commercial" revealed this about several of them.
    • Morgan and Cooper's total lack of any aversion to "Don't Hug Me I'm Scared". Royel in particular had seen it before!
    • William has seen most of the videos on the show, is rather snarky, and shares pretty deep insight on sensitive subject matters such as bullying or politics.
    • Dash, in particular, is quite articulate and snarky for being nine years old:
    (sees an old Mac computer) "How very hipster."
    • New girl Sydney may not be old enough to be snarky, but shows some surprising insight at times.
    • "Kids React to Girl on Motorcycle vs Littering". While some of the "victims" certainly earned their comeuppance, Tyler's the first one to say "two wrongs don't make a right".
  • You Bastard: The kids scold the viewers for having the Fine Bros show them Don't Hug Me I'm Scared.

    Teens React 

    Elders React 

    YouTubers React 

     Adults React 
  • Big Fun: Jonathan, the resident fat guy, seems like the nicest and funniest guy on all of Adults React.
  • Black and Nerdy: Dominic. He's the main black guy on Adults but he enjoys superhero comics and plays Super Smash Bros. 24/7, according to him.
  • Cosplay: In Adults React to Suicide Squad, Jennifer said she cosplayed as Harley Quinn multiple times.
  • Retool: The Fine Bros. once considered making a Parents React, but ended up sweeping that idea under the rug. Adults React is the recreation of that initial idea, being a combination of Young and Middle-Aged Adults note 
  • Perky Goth: Ary perfectly fits this trope. Alix is slowly becoming this as well, keeping her perky personality but becoming more emo as it progresses.
  • The Bus Came Back: This series marks the return of those who outgrew Teens React such as Tom, Alix, Madison, Jeannie and Ethan James. Briana and Victor ended up coming back as well.
  • The Big Guy: Beau is SEVEN feet tall.
  • Twin Banter: Allisyn and Kelli during gaming episodes.
  • You Gotta Have Blue Hair: Lotte, one of the newcomers, actually has dyed electric blue hair.

    React channel 
  • The Ace: Usually with some of the games played, there will be at least one teen who is either extremely familiar with the game, or who catches onto the mechanics with relative ease.
    • Newcomer Will has demonstrated his gaming prowess enough times that one of the other teens came up with a Badass Boast on his behalf.
  • Achievements in Ignorance: The long awaited Gaming with Five Nights at Freddy's. Sam realises the left door and light are glitched, then checks the tablet, causing Bonnie to jump him the moment the tablet goes down. Tom goes through the same thing, looks left and right and keeps hitting the switches without checking the tablet - and makes it to 6 am.
  • Adaptation Expansion: The first of the new React Channel shows (React: Gaming) basically takes the Let's Play-esque React episodes (e.g. Slender and Flappy Bird) and turns it into its own thing.
    • Due to the popularity of the gaming sessions, the Fine Bros. decided to expand the videos to twice a week to allow the teens to complete Let's Plays of the longer games like Outlast and The Last of Us.
  • Arrogant Kung-Fu Guy: Ethan James comes across as this, claiming he'd clocked in the most experience with Trials Fusion - before proceeding to come in second (with Adam and Jeordy tying for first place). Turns out his real strength was in the trick flip round, where he proceeded to get over 35k points, with the second placer at about 15k. And he's been known for Unsportsmanlike Gloating, though he does have the skills to back it up.
    • Comes full circle in the Super Smash Bros. Wii U competition, where Everhet ends up beating him with ease.
    Sabrina: I kind of suspected you were going to win though. I had this gut feeling cause like he was talking smack but I feel like you actually knew what you were talking about.
    • Troy gets to back up his talk when The Last of Us plays to his true strength, FPS.
  • Attack! Attack... Retreat! Retreat!: Sydney on unagi (eel) sushi.
    Fine Bros: Ready for your next piece?
    Sydney: I shall slay the beast!
    (Unagi sushi is placed in front of her)
    Sydney:...I shall not slay the beast!
  • Awesomeness by Analysis: The Super Meat Boy and Duck Hunt videos saw the kids and teens catching onto the game mechanics successfully through trial and error.
  • Blazing Inferno Hellfire Sauce: The Adults vs. Food episode for hot wings coated in different sauces have them try out different wings that start off mild enough, then crank up the heat with each one!
  • Cluster Bleep-Bomb:
    • In the second Outlast video, Adam says "shit" about 25 times really fast when he's caught. However, since the Fine Bros. censor the word, this is the result.
    • In the second PT video, Ethan James started Lampshade Hanging his excessive cussing.
    "I'm just gonna be cussing the whole time until we get there 'cause of f[bleep]ing bullsh[bleep] out in f[bleeping]ing bullsh[bleep] alley, in the town of This Sucks Ass."
  • Continuity Nod:
    • The second session of Slender is a fairly obvious one. Not only do they bring back some teens from the first one but their progress back then was listed, and Adam claims that getting only three pages became a Never Live It Down moment for him. And it was the best any of them did, too!
    • The first retro-themed Gaming deliberately reused the NES system from the first Teens React with retro technology.
    • The Gaming session of Trials Fusion immediately drew comparisons to Happy Wheels.
  • Damned by Faint Praise: In Kids vs. Food with caviar, Sydney said she preferred the crackers they put the caviar on.
    • Dylan was the only one to recommend natto, if only for the experience.
  • Failed a Spot Check: Dylan didn't recognize (cubed) tofu in it's titular Kids vs. Food episode despite eating it on a regular basis.
  • Foreign Queasine: Apparently the point of Kids vs. Food, but actually subverted as the items are a bit more common than you'd believe. Then again, Vegemite is an Australian thing so the "foreign" bit stands.
  • Fourth-Wall Mail Slot: Advice is all about submitting the same questions to Kids, Teens, and Elders.
  • I Ate WHAT?!: Happens frequently in [Kids/Teens/Adults] vs. Food, since "The Reveal" doesn't come until after they've tasted it.
  • Improbable Aiming Skills: Troy owns the FPS parts of The Last of Us.
    • Seth in Duck Hunt not only gets more than one perfect score, but manages to score hits while "just waving it around" and one time by looking away!
  • Incredibly Lame Pun: From Advice:
    TonyTigger: What are some good warrior names for my cat?
    Elle: Katniss! (beats out her own rimshot on the table)
  • Killed Midsentence: Don, when playing Call of Duty: Advanced Warfare, recognizes an area he visited in real life (Greece), he starts talking about his visit until his character gets killed unexpectedly.
  • Let's Play: This is pretty much what the React: Gaming series is, considering that it drops Question Time.
  • Mle Trois: The first ever Gaming with Teens head-to-head battle leads up to three teens throwing it down in Super Smash Bros..
  • No Sell: Everhet is the only teen unimpressed with Five Nights at Freddy's because he finds the gameplay boring. When he dies on the first night, instead of being freaked out by the jump-scared like all the other teens, he asks if that meant he won? The Elders as well generally had very subdued reactions to the game: a few of them did have fun with it, but the jump scares tended to make them laugh rather than cry out. When the Fine Bros. told them that some detractors believed that elderly people shouldn't play horror games for health reasons, they were alternately offended and baffled that anyone would think that was an issue.
  • Not So Above It All / Refuge in Audacity: Elders playing GTAV. At first they struggle getting the grasp of the controls. Then they marvel at the graphics and the variety of activities they can do in the game. And then they realize they have weapons and Hilarity Ensues.
  • Out of Order: Thanks to a bit of Schedule Slip, Megan and Shannon appear in Kids vs Food AFTER their debut on Teens React.
  • Pac Man Fever: In the first-ever Gaming with Elders (featuring Happy Wheels), Libby starts asking where the joystick is. Just think about that for a bit.
  • Previously On: Subverted for multi-part gaming series by not only showing tiny snippets of video that fail completely to provide any context. Immediately followed by "This time, on..."
  • Rearrange the Song: The theme tune for the React channel is done in different styles for each show.
  • Running Gag: Unintentionally, some sort of accident will befall Lucas in his appearances on Kids vs. Food, be it accidentally dropping the food (Tofu) or getting some of it on him (Squid ink pizza).
  • Screams Like a Little Girl: We get more and more of these with all the Survival Horror games suggested. You know whose fault that is.
  • Sequelitis: Tom's in universe opinion on Five Nights at Freddy's as a series is this. While he enjoyed playing the first game because of its simplicity, he feels the sequels aren't as good.
  • Something Completely Different: This episode of Kids vs Food is about... a perfectly normal cake. Turns out it's really a Milestone Celebration.
  • Spirited Competitor: Jasser during the Mortal Kombat Tournament. He quickly catches on to Sub Zero's moveset, allowing him to steamroll over everyone else. But then, he was also being humble about it, even giving his competitors pointers on how to play better.
  • Spit Take: A variant of the "Try to Watch This Without Laughing or Grinning" invokes this trope by having the participants do the challenge with water in their mouths.
  • Tastes Like Chicken: What multiple kids compared frog legs to in the corresponding Kids vs. Food episode. Likely justified because the legs were cooked similarly to fried chicken, so that was probably the first thing to come to mind as far as taste comparison.
  • Tastes Like Feet: Appears in Kids vs. Food.
    Samirah: (on salmiakki) It tastes like I licked a tablecloth. Yes, I licked a tablecloth before, I was really little.
  • Tastes Like Purple: Kids vs. Food, inevitably.
    Derek (on caviar): "It tastes like sadness."
  • Waxing Lyrical: This moment from Advice:
    Daenerys Targaryen: How do I become as fancy as Iggy Azalea?
    Troy: You can't become as fancy as Iggy Azalea, because... you already know... she's in the fast lane, from LA to Tokyo...
  • When Elders Attack: "Elders Gaming" with Grand Theft Auto V counts, kinda.
  • Wrong Genre Savvy: On "Kids vs Food—??????" the kids are shown a cake, and a few of them think there will be a cruel twist with what cake they get to eat, with one referencing how that happened on the Pizza episode. They're wrong; it's to celebrate the React channel's 1 year anniversary; the only "catch" is they have to eat it without utensils.
  • 0% Approval Rating: None of the ten kids in the "Vegemite" episode of Kids vs. Food liked the Australian delicacy.
    • Anchovies received a similar shut-out in the "Pizza Toppings" episode. You know it's bad when a few of the kids consider squid ink a step up.
    • Natto wound up being recommended by Dylan, but only so that someone could understand just how horrible it is.
    • Jellyfish also joined the list of "Kids vs. Food" shutouts. None of the kids were even able to swallow a bite.
    • Now you can add bacon-flavored soda to the list.
    • Ghost peppers were tried by the Adults...and none of them liked it.
    • Same thing when they tried cat poop coffee.
    • When it comes to Weird Burgers, none of the Kids liked salmon or canned burgers.

    React to That 
  • Adaptation Expansion/Adaptation Distillation: On the one hand, they leave out Question Time; on the other, they do a "Finish the Story" bit where the kids discuss the ramifications and fallout of the videos, and challenges where the kids get to mimic what was just shown. Also the "Try Not to Laugh" challenge done a couple of times on YouTubers React is now Once an Episode.
  • Lighter and Softer: While some of the teens are involved, they make sure to clean up the material a bit. Of course, it's no lighter and softer than the Kids React stuff.

Morgan: "Thanks for reading!"
Eric: "Let us know in the comments what we should check out next!"
Don: "If you liked this article, give it a big thumbs up!"
Royel: "An' you gotta subscwibe or the tropers will break into your kitchen and eat all your cookies."
Anthony Padilla: "And while you're at it, may as well subscribe to all of us."
Ian Hecox: "Especially the one with the two brunette guys. (not-at-all-subtle pointing) Right there. There. See that? That right there."
Vera: "To watch deleted reactions, click the box below."
Maksim: "Das vedanya!"
Lia: "Gimme a sec..." (staring into the monitor, clicking a few times) "No, later. (Beat) I'm just kidding, bye everybody!" (giggling, goes back to clicking)
