A drinking game. It's similar to beer pong and ping. You have one cup full of beer on each side of the table, and one in the middle full of water. The object is to make the ball in the opponents cup or hit it. If you make the ball in the opponents cup you immediately start drinking your beer till they shoot and make the ball in the middle cup of water. If you hit their cup you start drinking till they get the ball and put it anywhere on the table. The object is to be the first one done with your beer.
