Bell ping pong drinking game is a normal game of ping pong with a few minor differences.
The first is every player has a drink. They either take a shot or take a 1/4 glass sip of beer every time they loose a point.
The second difference is there is a bell dangling over the net (about 3 feet), if that bell is hit everyone including audiance members drink the required amount. (2-4 players required)
