Twenty-five years of morning radio will also cause Brian, much to his annoyance, tell people "Good Morning" from force of habit even though they record well into the afternoon. He's adapted this to "Good morning, afternoon, evening or whenever you're listening."
Brett Vanderbrook as Captain S has "Everything gets the Kick" during his first episode. It has been heard in a few other online shows since.
From the old CBUB, "Spanked like a four year old at K-Mart" and "Fat skanky redneck chicks". From the new CBUB, "It ends in sex".
Each member has their own, but the word "Brown" is used commonly by all of the Creatures, meaning bad, stinky, or used in place of a curse word. It was first said by Sp00n, but Kootra has since taken it, as he uses it the most. Also, the Creatures have said multiple times that it is in no way racist.
"MLG" when describing how good they are at a game (even if they aren't). This pokes fun at Major League Gaming circuits and serious gamers.
"I don't follow [X] news." used when someone doesn't know something or is corrected, the original being 'I don't follow Skyrim news'.
"Cheese it!" when the Creatures are running away or escaping from something in the game.
"High horse" used mostly by Nova, Seamus, and Sly. It's used to describe something that is very large, lavish, and/or over the top.
He opens most videos with "What's up everybody this is Critikal, I'm playing [game he's playing at the time], this is for [platform]. Let's do this shit!" and he usually ends each video with "Well that's the end of this video, remember to rate the video, comment the video, and subscribe if you want to see videos similar to this one. See ya."
"This is the greatest [X] of all time" for his video descriptions, where X is what is being done in the game. Sometimes can be absolutely false depending on the game being played.
In the webtoon GEOWeasel the character Mitri once claimed to be "Pretty much everywhere and nowhere, like a ghost or something." In later episodes, his brother would pressure him into saying it again, and then laugh like an idiot and proclaim it to be the funniest line in the world. This was probably a parody or a Take That aimed at several of the toon's fans who thought the line was so funny that they pressured the creator into adding it again.
Jimbob also had the Catch Phrase "Fix my saxophone", but it was parodied to the point that it became very irritating to everyone in the cartoon whenever he asked. Weas questioned whether the line was actually supposed to be amusing at all just by repeating it over and over and if it was leading up to anything (to which Jimbob replied cryptically "episode 15"). Later uses of the phrase either had someone stop Jimbob before he could say the whole thing or even ask or he would receive punishment for it (such as Weas shooting him dead in the first episode and stabbing him in the face in the long-awaited episode 15).
David Da Nugget is best known for repeatedly screaming "You're not f*cking Tony Abbott mate!" in GI Proz videos.
Several of the characters in the Global Guardians PBEM Universe had a Catch Phrase. The most notable were probably Force's "Okay, I want to try something..." right before he did something phenomenally stupid. This was almost always followed up by Recoil's "Great... Force is unconscious again."
Also, whenever he sees an attractive woman, he asks, "Wanna know my secret identity?"
Spoofed a few times on Homestar Runner. In Strong Bad's "crazy cartoon" "Sweet Cuppin' Cakes", the character of Eh! Steve seems to exist only to say his Catch Phrase, which is also his name ("Eh! Steve!"). At the end of the Strong Bad Email "the facts", Homestar says he's decided to change his Catch Phrase from "Seriously" to "That's bupkis!" Strong Bad used to say "Holy Crap!" with some regularity, as well, but due to inverse-Flanderization, he's been weaned off that aspect of his personality, and now groans whenever the word 'crap' comes up in an email.
Although he then began regularly yelling "DELETED" as he did so to many of the e-mails he was sent.
Parodied again with the Cheat Commandos, whose original Catch Phrase was "Cheat Commandos... rock rock on!"
Silent Rip: Uh... that's not what we usually say -
Gunhaver:(the Cheat Commandos theme music stops abruptly) Yeah, whatever, it's riggidy-roll from now on.
Parodied again with "Limozeen ...But They're In Space!", in which manager Teeg Dougland starts every sentence with "I'm afraid I have some bad news, boys."
And who could forget Teen Girl Squad's "Soooooooooooooooo good!", as well as Tompkin's characteristic Unusual Euphemism, "Awwww, peas!"
Bubs' alter ego, "The Thnikkaman," has several that either he says or are associated with him.
Kids: "Can we have some?"
The Thnikkaman: "Yeah, shut up, kid!"
Singers: "Here comes the Thnikkaman!" (When he leaves, it's "There goes the Thnikkaman!")
According to Homestar, Coach Z uses "You can't always rush into the score zone!" as a metaphor for everything.
Also, a standard call-and-response for private eye, crooked cop, secret agent, and celebrity pharmacist Dangeresque:
Reynaldo: Sounds pretty dangerous!
Dangeresque: No, sounds... Dangeresque!
"Looks like I'm gonna have to jump!"
Husky Starcraft: "Hello everyone, this is H-to-the-usky Husky here!"
Barry "The Blender" Henderson from the online Irish comedy series I Am Fighter has "What about you?". The phrase is (somewhat obscure northern) Irish slang for "How are you"? Of course, since the series has become so widely recognised in Ireland (moreso in the the North), the phrase has exploded in popularity. Barry's thick culchie accent makes it sound more like "Whadda boutchee?". It's frequently shortened to "Boutchee?", even by the man himself.
"That's almost a hundred..."Explanation: At various points throughout YGS' history, he's said something along the lines of "Episode X? That's almost a hundred!" It's only recently passed 50 episodes.
":a what a fucke?!" Explanation Ever since this entry from episode 21, he's used this sound bit/video clip/quote whenever he comes across a particularly baffling comment. Behold,all of them.
"Oh, Olga!" Explanation Fellow YouTuber/IRL friend Olga Kay, of Russian descent, has some trouble with the english language in written form (she's fluent in speech) despite living here for quite a few years, and Jack features one of her comments every once in a while in an episode of YGS, followed by him exclaiming "Oh, Olga!" He even slipped one into the Christmas Special, which is a song.
"Help me clean up YouTube! If you see an amazingly bad comment on the Internet, take a screencap of it and send it my way either via Twitter or my Facebook fanpage." Explanation His plug at the end of every episode for sending him possible YGS entries. He eventually turned it into a jingle.
"Let me know if I nailed it or failed it."
KateModern: After footage from a sex tape featuring him finds its way onto the Internet, Gavin accidentally gains the catchphrase "Keep your socks on!" At first he is somewhat embarrassed, but he quickly embraces it.
Later, there's also Tez On Toast, with his insistance on the need to "finish people off".
Nikki and John: Pranksters in Love - John frequently starts off videos by saying "What's going on guys, John here." and Nikki usually responds to getting pranked with "Are you f*cking kidding me right now?" At the end of videos, if John was pranked, a sound byte of John saying "Nikki, what did you do?!?!?" will play, while if Nikki was pranked, a sound byte of Nikki saying "Well that's just great!" will play.
The Chick used to have "I'm The Nostalgia Chick. I remember it, because the dudes won't," but later dropped it, revealing in an interview that she thought it was sending the message that girly movies didn't deserve to be remembered by guys.
Obscurus Lupa, during her reviews of Charmed, frequently repeats two truths about the show: "The Elders are dicks!", Daryl's "Aw, meng!", and "If it sounds like a good idea, Charmed will find some way to make it stupid." Also, when doing her Radu impression, she'll usually have at least one exclamation of, "Aw, damneet!"
R-Dash 5000: Man, these people are a bunch of freaks. Spike: No argument here.
"Nya" from the Process Forum.
The early Kids React videos had Lia describing everyone as "Creepers!" with accompanying hand movements. She stopped doing this after "Kids React to Minecraft" due to the explanation to her that some viewers confused her as a Minecraft player before then.
"Son of a bitch!" - said by anyone who's about to get blown up (or who's seen someone else nearby get blown up), usually one of the three versions of Church.
"My name is Michael J. Caboose and I! Hate! BABIES!" Even though he only said it once it still became his most famous phrase.
Whenever Sister says something shocking, someone will almost always say "Wait, What?!"
"Shut up, Caboose!" Said most often by Church, and sometimes by Tucker (and even more rarely by others), in response to Caboose's idiotic ramblings.
"Today is a good day to die!" Said by Sarge in the earlier seasons, but he seems to have dropped it recently.
"You fools!" Said by O'Malley to the Reds and Blues.
"Oh, Shut up." O'Malley resorts to saying this when Doc and Lopez argue with him.
Twilight Sparkle has an exasperated "Dammit!" as her default reaction to annoyances, of which there are many.
Night Moon Mare, in her limited screen time, says "Saaaaaaaaaaaand!" enough times to become a running gag (and to make Twilight complain). When she comes back as Princess Luna, her new catch phrase is "Blooooooood!"
Twilight: [Fluttershy] can also fix your catch phrase while you're at it. Luna: I have a catch phrase?
The episode "How to Control Freaks" hangs a big lampshade on the whole thing:
Twilight:[to Fluttershy] Are you serious? All you ever do is shout out the names of random black people! Rarity: And also she's shy and bad with animals! Twilight: That's another good point, Rarity. Fluttershy, quit hogging all the catchphrases! Fluttershy:You can't handle the catchphrases! Twilight:Dammit!
Whateley Universe: Phase (Ayla Goodkind) always says "Of course!" to the point where his friends parody it in-story.
"[subject] smoke. Don't breathe this!" - Tom Dickinson, WillItBlend
"(something) VS (that something)'s weight in (something else, usually chihuahuas)", "The (x) Jihad (There Is No Jihad)", "Hotbranch 3:16", "COW!", "Star Trek/The French Must Lose" and "The Simpsons/Star Wars Must Always Win" from WWWF Grudge Match.
