what did i do last night?

The question you ask yourself or your friends after a night of heavy drinking. Often, you do not want to hear the response, but need to know if you should apologize to anyone or get checked for STDs.
You usually spend the rest of the day dwelling on the events of the past night and slapping yourself on the head saying "doh!"

yo what did i do last night?
Danced with some drunk chick on stage at the bar and busted your ass

It just removes the word 'sex' to make it shorter, like any other slang term.

Ryan: "Yo man, what were you doin' last night?"

Jack: "I had yer grandma last night"

Ryan: "What the hell man?! That's sick!"
