An amateur insult comeback. It is often regarded as one of the worst possible insult comebacks, being criticized for its lack of creativity, low versatility, and manipulation of English grammar in the word "you."

The comeback was popularized by a scene from the 1985 film 'Pee-Wee's Big Adventure,' in which Pee-Wee Herman repeatedly says the comeback after being told a string of insults by someone else.
Mark: You should have let me copy your test answers in class today.
Jim: No, it's against the rules. Stop relying on me to bail you out all the time. You're such a blowhard sometimes...
Mark: Oh, yeah? Well, you're a coffee whore whose father is on crack!
Jim: I know you are, but what am I?
Mark: You're a loser who doesn't let me copy your test answers in class!
Jim: I know you are, but what am I?
Mark: -_- seriously dude
