If you party foul and spill a drink, you suck it up off the floor/table/the hot girl's tits. The nastier the floor, the harder the party should push you to zamboni. No floor is too gross to exempt you from zamboni. You often have to zamboni during beer pong or beer dice. The term originates from the device that clears and resurfaces ice skating rinks. You spilt it, so you have to clean it up, but with your mouth.
Todd tried to slap a bounce during beer pong, but knocked a cup over instead. ZAMBONI, TODD!
