A drinking game created at the University of Dayton. A combination of Beer Pong and Speed Quarters, where solo cups are filled a third of the way with beer and put on a circular formation. Two players start with an empty solo cup and a ping pong ball and try to bounce their ping pong ball into their cup. If they bounce the ball into the cup on their first try, they can pass the cup and ball to anyone else at the table. If they bounce the ball after their first attempt, they pass it to their right. If you bounce the ball into your cup and the person to your right has a cup already, you hit their cup off the table, yell loudly "BOOM!", and that person must drink a beer from the formation in the middle. The last person to get "boomed" has to drink a full beer.
