A drinking game played with one quarter and a tall drinking glass. Two teams are set up and one by one in an alternating fasion, players stick a quarter up their but and squeeze so it doesnt fall out. They then walk over to the empty glass and attempt to drop the quarter in the glass. If a player misses he/she must take a shot (or whatever). Winning team is the first to five.
They played butt quarters that night in the garage.
