bum tax

the money you have to pay a bum when he buys you liquor or cigarettes (if you're a minor that is). Generally you give them a twenty and let them keep the change, so they get in between 3 and 5 dollars for their services.

A: I've got just enough to buy a bottle!
B: I dont have my fake ID though. Do you have enough to cover the bum tax?
