An expression used by a character or group numerous times in a work. Merely uttering this phrase in the office will clue others in to the character(s) you're referring to.

To be a Catchphrase, the phrase must be repeated multiple times in an identifiable way — what is simply the most memorable line of a movie is not a Catchphrase unless it is repeated by the same in-universe character. When it's the audience that adopts a character's line as a Catchphrase, it's a Memetic Mutation. Conversely, when several different characters utter the same phrase at (or about) one particular character, that character becomes a Phrase Catcher.

Keep in mind that the distinctiveness of the phrase matters; something that's just a common expression needs to be said a lot more frequently to count as a catchphrase than something unique to the character saying it.

Some phrases are specific for character types, e.g. "That's against the rules!" for a Goody Two-Shoes.

If the character has a Badass Creed, it will probably double as a Catchphrase. Beam Me Up, Scotty! is a false or oft-misquoted Catchphrase. Compare Arc Words, One-Liner, Other Stock Phrases, Word Power. Contrast with Author Catchphrase, which is when a phrase is recycled across unrelated works by the same author/actor/creator.

Has no relation to the TV Game Show format Catch Phrase or the board game Catch Phrase (1994).
