look up any word, like bukkake:
An imaginary button that causes someone to become a complete jackass.

Coined by Bill Engvall in "Blue Collar Comedy Tour: One for the Road" when he was describing an incident during one of his flights.
Bill: Lady, I didn't get up this morning wanting to be a jackass...but you just pushed my jackass button.

A certain action that sets someone into a pissed off state. Everyone's button is different, it really depends on ones annoyances. Commonly performed by bitch ass niggas.
Vic: Don't you hate when someone sends you a text from somebody else's phone?
Joey: Yeah, that shit pushes my Jack Ass Button.
