Seeing the LJN logo on a game cartridge has also caused him to snap.
Which makes it even more funny when he finds out that Spiderman: Maximum Carnage on the SNES, which he considers the only Spiderman game that is good, was also made by LJN. The fact that LJN made a good game practically breaks his mind in the most dramatic way possible.
In Batman Part I, when he explains the utterly ridiculous controls of the SNES Batman Forever game, which was designed with the Mortal Kombat engine. He actually seems to have strained his voice by the end of the review.
AC adapters with built-in prongs (which tend to preclude the usage of the two adjacent sockets) also greatly annoy him, as seen in the Sega 32X and Dracula reviews. Related to this, ancient consoles which force the player to make use of an RF connector box for television hookups as opposed to just plugging a cable into a much simpler coaxial converter.
Any game that has annoying design element that just makes the game more irritating to play—Kid Kool is one example he particularly singled out, where he lists numerous design flaws (fittingly named "Seven Deadly Sins of Game Design") that blatantly hamper the experience, such as "One Way Bullshit" note Referring to the games Ratchet Scrolling, which can cause you to accidentally lose your method of attack "Topside Aquatic Ass" note A bizarre game mechanic where you have to do a mandatory jump by skipping across water three times, with the third time having to be perfectly timed or you die on the spot and "Two-Gear Diarrhea" note You can only run at two speeds, super slow or at uncontrollable speeds, and this also ties into the fact that the limited view ahead of the character makes it easy to collide into enemies, and some jumps require you to build momentum on very tiny ledges .
If you don't think he can be overwhelmed by annoyance in how lacking in depth a game is, jump to 3:03 of this episode and note a problem at that point that got missed. If you're wondering, let's just say it's not exactly a challenge to get a high score in that particular game due to evidence that the game is INCREDIBLY incomplete.
Out of his usual complaints, games with bad controls seem to be the chief problem. Generally, he can forgive a game for having bad graphics, obnoxious music, or obtuse clues, but never if it's a chore to actually operate.
Games with inconsistent and/or unfair rules really throw him off the deep end. Beetlejuice for NES is notorious for this ("Diarrhetic Diversions"), where you can fall to your death if the floor below is not on screen (the "Bitch Barrier") and yet can be hurt by torches not on screen.
As seen with Dick Tracy and Total Recall, the idea of going to the video store as a kid and renting a game that turned out to suck, since it was the one game he could play that whole weekend, thus ruining his weekend.
Guns; specifically guns and kids. For his Wish List Christmas episode The Nerd was horrified by children's toys advertised alongside enough guns to resemble Charlton Heston's Xmas catalogue. Which makes sense, in an earlier video he reviews The Odyssey which included a gun: unpacking it and when showing it off he showed very good gun safety despite it being a toy.
Ray hates the cake item. He'll smash it on sight and once dug out of his own home when Gavin and Geoff sabotaged his home to shoot cake out of the walls. Also, as a fan of Sailor Moon's Tuxedo Mask, don't mess with the roses. Just don't.
Gavin Free is a troll, no ifs, ands or buts about it. But, stoop down to the point where you're cheating and he'll take offence at that. As well, as an Ill Boy, Gavin doesn't entirely enjoy a Groin Attack.
By extension, do NOT joke about animal cruelty.
Don't ruin something Geoff put a lot of work into. He'll drop his controller and start pounding the shit out of you. In Real Life.
Though part of the larger Rooster Teeth family, don't mention Las Vegas to Gus.
Flocculencio in AH.com: The Series whenever anyone mentions the name of his nemesis, Justin Pickard. Particularly noticeable considering Flocculencio is usually one of the more laid-back and sedate characters, but this makes him go Ax-Crazy.
It might seem redundant to give the Angry Marines a Berserk Button, as they're always angry, all the time. But something that'll really set them off is Heresy. Any mention of Heresy within earshot will have them grabbing their weapons and attacking the nearest object, or the ground if there's nothing else in sight, looking for the source of the Heresy.
Don't dig up Linkara's old fanfic, force him to listen to you read it, and then have the temerity to insult Doctor Who. When Bennett the Sage pulled this stunt, Linkara escaped the ropes holding him into a chair and started laying a smackdown.
One More Day and everything to do with also tends to send him into fits of rage.
Apparently, a comic adaptation of Star Trek II: The Wrath of Khan getting the movie's famous KHAAAAAAAAAAAAAAAN!!!!!!! scene incorrectnote The comic reduced that particular bit to just one panel and Kirk just simply shouting it. is enough to cause Linkara to just absolutely lose it.
False advertising (announcing bonuses which don't appear, Director's Cut when it's the theatrical one, etc.)
Ab 3 of The Binder of Shame kills off player characters for making Monty Python references and, after excessive experience with El Disgusto's God-Mode Sue habit, now twitches every time someone mentions ninjas. El Disgusto himself flies into a rage when someone intentionally or accidentally refers to the time his dog bit his penis, unsurprisingly.
boogie2988's character, Francis, has many of these, but the biggest by far is when he thinks that someone is making fun of his weight.
Maffew of Botchamania seems to have a minor one, which is misuse of the phrase "Couldn't Care Less."
Don't ever try to continuously fart near Mewtwo, or else, even at the cost of his own job, he will end up mind-wiping you, as Wario learned the hard way.
There are 2 things that Ganondorf does not tolerate: Vaati implying that Ganon's time as a villain is up, and villains not getting the hint that they were not accepted into the group. He blows them up to the shock and horror of his comrades.
Do not go on the Mass Effect RP site Cerberus Daily News and try to sell slaves, unless you like having armies of enraged mercenaries trying to kill you.
Chakats. Let's count the buttons, shall we? Harming children in general? BEATINGS. Kidnapping/harming one of their own kids? WORSE BEATINGS. God help you, killing one of their own kids? You'll be lucky if there's enough of you left to bury.
Both Cactuar and Tonberry from the Final Fantasy series by Crazy Boris have theirs.
Tonberry is eventually pushed to such a breaking point by Cactuar's stupidity that he sets the poor idiot on fire— twice— in "Gil Quest".
Cactuar goes ballistic upon being called "Fatty" by a cop in "Final Fantasy: Fugitive", and proceeds to morph into a giant, psychotically violent, needle-throwing version of himself. If a fleet of fighter jets arrive, he turns back to "normal" self, but saying "ARE YOU KIDDING ME?" and runs.
He also gets really pissed at Aerosmith for misspelling his name in "Resident Cactuar".
And whatever you do, DON'T mention Mary Kate and Ashley around him...
In another one of Crazy Boris' animations, Dimwit Quest, don't even think about trying to take Jim's bag of Powdered Sugar.
In Darwin's Soldiers, a group of thugs at a food court insinuated that Aimee, who has robotic arms, was a cripple. Seconds later, five of the thugs were dead.
In the 3rd Darwin's Soldiers, the Horseman of Death just killed Neku's girlfriend Hailey. This was a very, very bad idea. Neku is now in a hyper mode that BURNED HIS SKIN OFF, and is now out to slaughter the remnants of Dragonstorm. And anything that gets in his way.
In Database Rangers Power Reviews Just as in Power Rangers RPM, never, ever say the word "spandex" around Dr. K, especially regarding the suits' material. Just don't.
Do not hug Dracon. He doesn't need a hug. He needs you to stay far away.
Anna Demorah, in Felarya, tends to be somewhat cranky, but she'll leave you alone... unless you make the mistake of smoking in front of her. The fact has come up so often in fanfiction that it's rather killed the original humor.
Fighting Leaf does not approve of jokes made about a child's death, even if it's fake, especially ones made by the villain.
In Freddie Wong's short Don't F With My Cream, two robbers who knock over an ice cream parlor learn a verypainfullesson when they mess with Freddie's ice cream.
The two guys whose fighting ends up destroying the work of the Sandcastle Sensei also don't get out of things unscathed.
Gordon Freeman, at least as interpreted by Freeman's Mind, isn't the most stable of individuals by any means, but what really sets him off are bugs, which he will chase while flailing away with his crowbar before pulling out an MP5 or shotgun. He also gets upset when confronted with yet another locked door or dead end.
In Dragon Ball Z Abridged, Goku takes Christmas very seriously. Do anything to jeopardize it, and you may not live to see New Year's.
Don't hurt Piccolo, threaten his friends, or do anything to remind him about his father's constant absence or else Gohan will beat the tar out of you.
When someone refers to Goku as more important than Vegeta, you have pressed the (as referred to Future-Trunks) Goku Button (Episode 49).
Mr. Popo is already a rather unpleasant individual, but any display of incompetence at your job will ensure he hates you. And if you call him "black man" he will likely throw you off the Lookout no matter who you are.
Jon will actually devolve into angry cursing mid-sentence if Arin belches. It almost makes him physically ill in Part 30 of Sonic 06.
One of the Grumps has never seen The Lord of the Rings. This revelation causes the other Grump to cough blood. (Sonic #57)
Jon: It's just like, "durr, I haven't seen Star Wars..!" Arin: What the fu— There's a lot of people who haven't seen Star Wars! Jon:FUCK THEM! Arin: Corey didn't see Star Wars, and I just showed it to him last night! Jon: Corey hasn't seen Star War— (indistinct) GET OVER HERE YOU PIECE OF SHIT! I'm gonna go beat him up!
In Pokemon Emerald episode 13, Jon and Arin talk about how one night, they went to Disneyland during grad night and, while riding Star Tours, most of the grad night students were yelling obnoxiously about how awesome they were. At the end of the ride, Jon, who had politely asked them to quiet down before, ends up yelling at them for being rude and disruptive throughout the whole ride.
Back in his own show (and on panels related to it), Jon seems to hate it whenever his sleeping habits are criticized.
I made it past age 18, I pay my bills, I pay my taxes, I'll sleep whenever the fuck I want. Fuck you.
WHO THE FUCK ARE YOU TO TELL ME TO GO TO BED!?
In the short lived zombie webseries Hells Paradise, don't suggest the beach as a meeting place to Jarid. Jarid. Hates. The beach. Also, don't kill Keane's best friend. He will freak out.
Hoodoo Hoodlum's revenge: Bad Creepypastas, especially Jeff the Killer. Behold
In The Gamer's Alliance, Belial is a reasonable and polite fellow even to his enemies. However, those who insult his loved one Razia in front of him will quickly regret ever opening their mouths.
From the Global Guardians PBEM Universe: Never, ever mention the fact that Dreamcatcher's father died in an insane asylum after a life of villainy if you value your sanity. Dreamcatcher, as the name might imply, can manipulate your nightmares so you regret ever mentioning his father in the first place.
Want to press Eightball's Berserk Button really, really hard? Make fun of Bamm-Bamm's condition or use any variation of the word "retard" in his presence. Go head. I double-dog dare you.
The Hitler Rants videos, particularly the commonly-used bunker scenes, involve Hitler himself melting down over anything, no matter how trivial. He also doesn't take well to the antics of Hermann Fegelein or Jodl's objections.
Religion. Even if it's worshiping him. Especially if it's worshiping him.
Committing Heroic Sacrifice when other, less suicidal options were available, and wasting irreplaceable battleship to do so. He's willing to forgive, though, if it accomplishes something meaningful.
The Traitor Legions. His anger at this line of thought makes the loss of an Emperor-class battleship look tame by comparison.
Not fighting in a melee. When he learns that Tau avoid close quarter combat, he's one step from ordering them exterminated.
Other characters have their own as well: Kitten gets uncharacteristically furious at any mention of Tau and Marneus Calgar practically starts foaming from his mouth at any mention of his Chapter's Mary Sueishness.
When it comes to Kitten, it gets even better/worse when anyone mentions his relationship with Shadowsun. He gets so furious, even Magnus leans back.
Speaking of Magnus, he tends to be Enraged by Idiocy, and has bouts of impressive nerd rage if you start audibly flicking your cards while playing a card game, but he truly goes berserk when anyone brings up the Space Wolves, and especially Leman Russ, who he despises.
The last one's mutual; mentioning Magnus to Leman Russ will send him into a Warp-shaking Tranquil Fury. There's also pretending (whether you believe it or not) that you're the Emperor in front of him, which will lead to a Megaton Punch.
Don't call Fabius Bile "Bob" even if you're one of the Chaos Gods' greatest champions; he will try to knock you the fuck out anyways.
Rogal Dorn will get "slightly infuriated" at the repeated destruction of perfectly good furniture for the sake of shitty slapstick. It doesn't sound like much, but he is massively stoic and the fact he even reacts to this is notable.
Cegorach is not the sort you want to meet even when he's in a jolly mood. Insulting his Harlequins or their material is a quick ticket to pissing him off, and unless you're Ephrael Stern or someone on her level he'll make sure you meet a terrible end.
Jeff, the hero of Ewen Cluney's anime-inspired story "Interesting Times," is a nice guy, if something of a Weirdness Magnet. But that comic collection that he maintains? Don't mess with it. You will not like him if you mess with it.
A number of characters have one of these in The Mad Scientist Wars, most noticeably Andrew Tinker. No matter how tempted you are, or how true it is, do not call him 'girly' or refer to him as female. The last guy got pinned to a wall by his neck.
Kora, leader of the Media Whorz round table has no tolerance for bad movies using legendary quotes from great movies. When Uwe Boll's Bloodrayne film used a quote from The Godfather, he got angry enough to break.
The Mark Remark: After the announcers claimed that Sin Cara stands for "You're eliminated", Martin was very distressed the next episode to find they said it stood for something else. Now whenever they can't decide what it stands for, Martin breaks a pencil.
J from Misadventures Of Awkward Black Girl hates when people touch her stapler. She ends up being forced to go to an anger management people with other people whose pet peeves include e-mails written in Comic Sans and people who don't let the microwave time run out.
Do NOT brag about torturing Sonya Blade in front of her partner, because Jax will punch your eye out (and this is before he gets his bionic arms).
Fading actor Johnny Cage pitches an idea for a new action show, but the executives turn him down, saying action is no longer in. As he's leaving, he overhears the executives using his idea, but offering it to an actress as the lead instead. Johnny gives the executives and some intervening security guards a No-Holds-Barred Beatdown.
Threatening the family of General Hanzo Hasashi (AKA Scorpion) is likewise a bad idea. As for killing them, well you might want to get your affairs in order. Not even death will stop him.
If you're a Player Character, do not look Cameron in the eyes. (Justified - he is an Enderman, after all.) Unlike most Endermen, though, he just gets PO'd, and can easily be pacified by amazing him somehow (which isn't hard to do). It takes two glances to unleash his demonic fury. God help you if you do that.
MSF High Forum: Fortunately, Mitchell (as an obvious example) keeps this strictly to real life, never letting it interfere with his duties as a GM. (Mainly, it's people who try to start R Ps over IM while he's working on MSF High, though he often simply logs off and cools down. He has gone into Angrish before, however.)
In NoobSparadrap of all people has three of them. Insulting his grandmother and hurting his friends are already bad enough, but if you really want to anger him, kill these pets he's constantly talking about. Preferably via burning the bag that contains them all.
Whenever the game decides to rendomly drop Bob's Brain, an item he considers utterly useless.
Whenever the game decides to spawn The Haunt, especially while he's playing as The Lost and getting a lot of good items beforehand, since The Haunt is a rather difficult enemy and he tends to die a lot to him.
The "Bat Credit Card" and Doug drive him to psychopathic rage. By Christmas With The Kranks/Bunny Boobies, both still make him angry, but he's more pissed off and upset that people keep wanting him to do both freak outs over and over. (Doug said in a 2012 interview that the former meme has given him a twitchy eye.)
He can't stand children getting abused or having a film treating them like idiots and women not having the power they should have.
He also hates it when a parent death is treated solely as a plot device with little emotional resonance.
Movies based on historical tragedies, like the animated Titanic films and Pearl Harbor, get a lot of hate for mis-portraying real disasters where thousands of people died for the sake of narrative or dramatic convenience.
Since the show began again in 2013, the Critic despises TMZ.
Even after the reboot, he hates it when people bring up Doug. In the "Disney Afternoon" episode, when Malcolm said how good Doug was, there was a cut and Malcolm nursing a black eye and couldn't feel much in his mouth.
Additionally NEVER, ever sing or play the Doug theme song (Nick version) in front of Doug Walker or he will murder you.
If a movie has heavy-handed symbolism and religious metaphors, the Critic will show it no mercy.
He would also kindly like you to not say the proper name of DT because the theme song finally got out of him.
Despite him lampshading that they ended in a sweet place at To Boldly Flee, a little girl gets beaten to death (offscreen) because she mistook him for the Nerd.
One that he will dedicate entire episodes to are frivolous copyright claims to silence criticism that could hurt profits and reputation. See: Tommy Wiseau, Hollywood in general...
Apparently though Dan Rizzo was doing a bunch of corrupt things behind everyone's back and abusing his admin powers, so he was already skating on thin ice at that point, that was just the final straw.
Doug is furious with the very idea of the "State Home For The Ugly" from The Garbage Pail Kids Movie, as shown here. Apparently the anger shown in the NC review wasn't played up for laughs, since he goes into a legitimate boiling rage while discussing the film after remaining relatively calm when discussing the other ones. He then delivers an especially brutal "The Reason You Suck" Speech at the film by saying it was worse than Manos because at least that was made by a farmer with no budget and wasn't intended for kids. He further goes on to say that the only good thing about the movie is that because there is nothing remotely good about it that it'll be quickly forgotten.
During his review of King's Tommy Knockers, he started ranting about how the deputy's husband not only was cheating on her with some woman at the post office, but also throwing away food she made for him, laughing at her behind her back, and sleeping with his mistress rather than looking for a missing child. He must have strong values if all of this bothered him.
In general, Nostalgia Critic also gets upset when he feels that a movie or TV show has been half-assed, or when movies and TV shows are condescending to children, either by pandering to their intelligence or, as stated before, being half-assed. His hatred of not putting effort into things is so great that it spawned a 10-minute rant at the end of his review of The Christmas Tree because he believes that Christmas requires genuine thought and effort to truly be special and joyous.
Professor Otaku is prone to bringing himself to the brink of sheer breakdowns, but more often than not reigns himself in. However, MD Geist and Sorcerer Stabber Orphen Revenge have seen him lashing out at his hated foes of Moe and stupidity rather loudly.
Vixen wound up in such a rage that she denied her traditional Chill-out Food a mere 10 minutes into New Moon. The terror that was wrought on the universe will never been erased.
Unless you want to unleash Tranquil Fury, don't insult JesuOtaku's boyfriend Nash in the comments on their videos (especially for using an e-cigarette without knowing what they are), or directly attack him, his taste in music and his fans on the chat for his live radio show. The reaction you'll get can be best described as Linkara's reaction to Lian Harper's death in Cry For Justice, but directed at YOU!
Cin Wicked blows a fuse over the Canadian music groups on display at Disneyland.
Most Protectors of the Plot Continuum agents have a Berserk Button of some form or another. Common causes are messing with favourite characters, breaking the English language, trivialisation of child abuse, or misogyny, which offend the PPC community as well as in-setting.
It's well known that ProtonJon of Let's Play fame hatesInvisible Coin Blocks. Naturally, people sent him tons of Mario Rom Hacks with egregious levels of invisible coin blocks being used in tedious ways. Initially when he's angry he sounds like Ren from Ren and Stimpy, but over time it gets less comical and more like Regan from The Exorcist. Eventually Jon got so ticked that he responded by creating an incredibly tedious rom hack level himself with nothing but invisible coin blocks, and promised to make more levels with other things that irritated him if people didn't lay off some of these tricks. Here's a video of another Let's Player going through the level. To quote a youtube comment:
He also seems to have quite a dislike for people who think adding crafting to a game (in particular, RPG games) makes it better. He gets quite indignant in a number of the "Kickstarter Non-starter" videos involving games decides to throw in a crafting element.
The cast of Rocher Hotel have a few, with one example being Luke's supposed addiction to amiibo.
ProtonJon hates all of his old CatchPhrases being referenced, but special mention goes to "MOVE FASTER POKEY!" and "Don't eat the mushroom.
Both he and Chugga also seem to get annoyed when people take their Vitriolic Best Buds relationship in the videos seriously, since the two are actually good friends in real life.
NintendoCapriSun, though generally the quietest and nicest of the three, has a Played for Laughs berserk button in the form of green rupees. He also has a straight version in the form of his own constant failures, which usually result in either a Big "WHAT?!" or him temporarily becoming a Deadpan Snarker.
Sonia, from The Saints, hates the in-universe book and film series Bone Eclipse.
Sam & Mickey: The phrase "Dijon mustard" flies Barbie into a rage, because it reminds her of when a perfect dinner party with Midge and Alan went downhill due to a lack of the condiment.
SCP-076-2, code-name "Able" is Ax-Crazy nearly all the time, but if he ever sees the symbol on SCP-073's (code-name "Cain") head, he goes utterly berserk and drops everything to attack Cain.
SCP-096, code-name "Shy Guy" is normally passive and no threat to anyone. However, if anyone sees it's face, in person or through a photograph or video footage, it enters a screaming fury and runs towards the viewer at breakneck speed intending to tear the unfortunate person limb-from-limb, and nothing will stop it. It doesn't flinch at high-power weapons and will tear through concrete to get to you. Because of this, 096 is a huge threat to the public if it escapes; if an image of it's face was put on the news...
SCP-261, a sentient and multiversal vending machine, will try to poison you if you use counterfeit money with it. The coin-on-a-string trick is also a way to get on its bad side; it used to cause the machine to simply give you food that you'd puke back out instantly, but it got so tired of that it dispensed a live grenade and killed several of the testers involved.
SCP-457, the so-called "Burning Man", hates water.
SCP-516, the "Intelligent Tank", despises traitors to its country, and will blow them up without its usual restraint.
Being a family man, his anger is prevalent in the VOY episode "Real Life" during the clumsy use of a dying child as a plot device.
He has a low tolerance for 'zany' scenes of childbirth. His "Annoying Character" award for "The Begotten" went to everyone involved in the childbirth B-Plot. Everyone.
Episodes with Star Trek's "Prime Directive," are known to make him especially furious. He compares it to "Watching a child burn to death trapped in a car, and listening to it scream and beg for help... and then calling yourself a hero for letting it die."
He absolutely hates Good Old Ways aesops, pointing out how technology has improved our lives. He can tolerate scientific flubs and technobabble, but insinuating that cavemen are morally superior really grinds his gears, to say the least.
It's best not to give Mutahar of SomeOrdinaryGamers under-cooked chicken. He will not appreciate it.
Considering that he also reads and gives thorough critiques of various short horror fiction and Creepypastas of varying quality, there are of course a few Pet Peeve Tropes he has that he would really like to see less of. s, Tears of Blood, Hyperrealmism, to name a few.
Their review of Maid RPG has them joking and laughing about the RPG and it's quirkiness, but as soon as they get to the page that has stats and NPC behavior advice for the ghost of a little girl and said advice revolves around what to do if the PCs seduce her, they drop the idea that it's just a harmless anime-inspired RPG and start calling it out.
Oh, yeah, and don't praise any Sonic the Hedgehog game past 1999 on Sonic Retro. You will be trolled.
There's a lot more, but these are probably the biggest.
Stuart Ashen has a few things that tend to draw out his ire in reviews, the biggest ones being lanyards and "MOTHER!FUCKING!REPAINTS!" of figures. The latter one was so bad that in one video, he refused to burn them himself, instead giving them to a friend to (ahem) dispose of them in more creative ways.
NEVER mess with Black Yoshi's Call of Duty or ask him to play 2 Player. If you know what's good for you, you won't destroy his Xbox One, either. And don't even think of pranking him, as if you do, he'll definitely shoot you.
Don't eat Shrek'scheesecake. You'll be sure to have a bad death, as Toad found out in "Toad's Mistake 3".
If you're playing trains with Bowser Junior, don't ever play with Thomas, even if he has more than one, as he always wants to be Thomas. He'll make you play with another train, most commonly The Ugly Red One note Salty in the Thomas the Tank Engine series. Also, don't ever say anything positive about Big Hero 6 around him.
One thing that irritates Cody the most is Junior telling him the Sun is a planet. This has gotten so bad that Cody actually shoved Junior down a set of stairs when he said it. Cody also doesn't like not appearing as a playable character in Mario sports games, especially if the game has room for alternate forms of certain characters (Metal, Baby, Cat, etc.), but not for a Magikoopa, as seen in "Cody's Missing!".
Jeffy's obnoxious behavior is a big button for Mario, even more so than that of any of Mario's friends. Mario's also driven to an almost Ax-Crazy state whenever he sees turtles.
Don't ever call Tyrone Calvin by the N Word or by the F-word (the other F-Word). You'll be sure to suffer Amusing Injuries, as Bowser Junior and Mario both found out in "Bowser Junior's YouTube Channel!", and "Jeffy's Bad Word!", respectively.
The bad treatment from Bowser and Junior is a big one for Chef Pee Pee. It got so bad at one point that he ended up quitting. Also, tricking him into believing that a family member died will result in a huge rant from him.
Jeffy does not like being called "Bad". Also, giving Jeffy dollars when he loses his teeth will result in a swearing fit from him, as seen in "Jeffy Loses His Teeth!". Jeffy will also fly into a rage at the mere sight of green beans.
A few characters have at least one in Survival of the Fittest. For example, in v3, Darnell Butler has his protectiveness towards women extend towards being compelled to attack anyone he sees severely mistreating one, and Bobby Jacks becomes uncontrollable when called a murderer, causing a fight at the senior year's bonfire and, eventually, driving him to murder Tyson Neills. Especially notable since this seems to be the only thing that can make Bobby actually snap or get angry at all.
Unassuming little Hazel Callaway breaks bones whenever somebody speaks ill of her mum.
Steff has a large half-ogre boyfriend who is very, very protective of her.
The crew of Talk Radar does not appreciate people who call them biased, or ones who imply that they've accepted money for review scores. Many of them went to journalism school and see lying to their readers and listeners one of the worst things they can do.
In Tech Infantry, Erich Von Shrakenberg has a bit of a thing about aliens, and about rebels who compromise humanity's unity in the face of the alien threat. And then there's Hex, who alternates between flipping his lid whenever someone calls him "Hex," and flipping his lid whenever someone calls him anything but "Hex."
TV Trash: Chris "Rowdy" Moore (the character, at least) has gotten pissed off at a lot of bad TV. He finally went over the edge during his review of "Road To The Multiverse", in which a Disney styled sequence turned into a stab at Walt Disney's rumored Anti-Semitism, by having Mort BRUTALLY assaulted. He goes into the other room to scream, and he comes out with a rant that makes "The Reason You Suck" Speech he gave to Seth MacFarlane just two episodes later seem MILD by comparison.
Derek the Bard has a laundry list of them: Damaged library books; stupid weaknesses; people trying to steal from, infiltrate, or otherwise harm the Library; Adaptation Decay; deus ex machina abuse; lazy writing...
Longram from We Are Our Avatars hates genocide and anyone who inflicts misery on the innocent. Reckless Gun Usage is another as he demonstrates this by confiscating Pinkie Pie's plasma gun during an incident in battle.
Nolan North's presence in a game is something that will easily earn the ire of Yahtzee. He claims to not hate the man himself however, just his voice.
Whether it has to do with that countdown or not, he seems to take issue with pros who make rookie mistakes in their work. Like a voice actor in RWBY checking his mic on the job.
Hades: "You left the sound of an adjusting microphone in your PROFESSIONAL, SOLD-ON-BLURAY WEBSERIES!! *sigh* We'll tolerate you..."
YouTube microwave guru Kenny Irwin (known also as "dovetastic", "dove" for short) is generally very cordial and accepting of dissenting viewpoints, even thanking people for taking the time to watch his video that clearly disliked it. And if you find his dislike his narration, he won't argue with you since he dislikes his own voice. He also supports other microwave shows. However, there are two ways to push his berserk button. The first one is by claiming that he's copying Is It a Good Idea to Microwave This?, a show that started almost a year and a half after his did. The second one is to insult his religion. Any comments about destruction of the Qu'ran or hateful comments about Islam in general will also draw his ire. Repeatedly insisting that he's copying the other major microwave show or insulting Islam will result in being permanently blocked. He's stated repeatedly that it's not Jon or his microwave show that he dislikes, it's the fanboys that spam other microwave shows with hateful comments.
Simon Lane has a Played for Laughs variation. Bringing up the Bees in Minecraft attached to the forestry mod gets him screaming mad in just a few seconds. He blames them for the Jaffa Factory series getting the hatchet (even though there were more legitimate reasons).
After Sjin betrays Kim Richards for Sips and blows her up, she understandably develops a hatred for SipsCo and angrily reminds Sjin about it on a frequent basis.
Rythian is really tired of being asked when the next episode of The Blackrock Chronicles will be out.
In The Little Wood gets very defensive over Lapis Lazuli, and so much as saying anything bad about it is a prime way of getting your butt kicked.
Suffice it to say that Turpster's car giving out in the Heroes And Generals miniseries, plus Lewis, Simon and Duncan Jones prank-calling him and pretending theirs had (to deliberately annoy him), left him fairly hacked off.
Never, EVER kill Kim Richards's pet penguin Billy. She will hunt you down to the ends of the earth.
Killerbunnies has Jemima's being called a "fatass" considering that she's injured twelve children for doing that.
In the youtube series Pokemon Pals, if you mention Brock's eyes, he get super pissed.
