Master Chief's "lol remember arbitur?" Lampshaded in "Drunken Halo".
Arbiter: Don't forget you admitted you were terrible. LOL, remember Chief? Master Chief: HAY / thats mai thing arbitur / u cant use mai thing / remember / remember its mien / lol remember arbitur? Arbiter: LOL, I remember Chief. Master Chief: LOL / ur so silly Arbiter: I know, LOL. Master Chief: LOL
Whenever someone says "needy", Needle immediately slaps the person in offense, exclaiming "don't call me Needy!". Sometimes she'll add "but no" when answering a question.
Eraser often asking what the contest is.
Announcer: Okay, enough talking. Let's get to it. The ninth Eraser: Which is?
Also, Eraser will at first shout "Yeah!" when he gets a reward, but followed by "Aw!" upon receiving some unfortunate side news.
Bubble exclaims "yoylecake!" in excitement.
David's "aw, seriously?" Needle sometimes says it too.
Lightning's "so to clarify..."
Pin's "what, that's crazy!"
Yellow Face's "YAY!"
Bomby when ignited will shout a decipherable "OH NO FIREY! YOU LIT MY FUSE!"
Fanny often exclaiming what she hates.
Fanny: I HATE (topic in question)
Since Cary Huang can't voice Ice Cube anymore, several of her lines are constantly recycled. One includes her need for revenge on others, "I want revenge!"
Ben T. Looney has, "Welcome back to Ben Rants/Salutes/'s Top Ten, and when I was a kid [X]."
Most of the videos conclude with Ben saying, "I'm Ben and I'm signing out. I'm gonna/going to [X]."
Jack and Trixie share two, both being responses to insults they can't disagree with: "That's tough, but fair" and "That's probably true, but you still shouldn't say it." Usually said in the middle of one of their usual Snark-to-Snark Combat sessions. They're also prone to tell one another that "I hate you" whenever one annoys the other.
One occasion takes advantage of the nature of catch phrases as something people say so the time, often without thinking about it. When people call Trixie "Miss Dixon", she typically responds with "Trixie, please!" She's apparently so used to this that she's not even aware she says it. This contributes to the solution of "The Reunion" when Jack stops Trixie from doing it while the woman they're speaking to, a woman they'd met previously doing a Twin Switch, reveals herself by calling her Trixie.
Bowser's Kingdom: Steve has "Hi, guys!" even though he says his never-before-said-onscreen catchphrase is "Who'd taken all the ketchup?" in episode 10.
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 Catchphrase "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).
Lumpy from Happy Tree Friends always says "Mmm hmm" after he thinks he's done something right.
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 Catchphrase, 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 Catchphrase 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 Catchphrase 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've got 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!"
Or:
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:
Renaldo: Sounds pretty dangerous!
Dangeresque: No, sounds... Dangeresque!
"Looks like I'm gonna have to jump!"
In his sbemail "the process", Strong Bad mentions how he likes to start his email replies with "Well, whoever, something something something" or "Something something, eh, whoever?"
Larry Palaroncini of Limozeen has "Well ALRIIIIIGGHT-uh!"
King of Town's "Doo hoo hoo!" could count, as well as "Poopsmith!"
The Liquid Generation series Masterpiece Movie Reviews has a few of these for Professor Butterhands.
"Hello, welcome to Masterpiece Movie Reviews. I'm Professor Butterhands. This week, we'll be reviewing [movie] which is/was originally titled [joke(s) based on its title]."
Butterhands wraps up each telestration by drawing an "X" over the current screencap and saying "Next picture!" If it's the last screencap, he draws a few lines over it while saying "No more pictures!"
Starting from Season 4, "Bow chicka bow wow" becomes Tucker's catchphrase, and something he tends to say at least Once a Season.
Sarge has two phrases that could count as his:
"Dirtbag", a word he usually uses to describe an enemy, or really, anyone who happens to be pissing him off at the moment.
While not used as often, "You just got Sarge'd" is something he also tends to say before or after finishing off an opponent.
Caboose has two phrases that could count as his:
While he doesn't use it often, "Neat" is something Caboose has a tendency to say, usually in response to things that would warrant a much bigger reaction.
Whenever Caboose does something wrong, he'll usually follow it up by saying "Tucker did it".
Sheila always says "Firing main cannon" whenever her cannon is about to be fired.
Agent Wyoming has "Knock-knock" as a catchphrase. This is a phrase his A.I., Gamma, tends to say a lot a well, so it seems to be something that rubbed off on Wyoming.
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.
