A more complex hardcore alteration of beer pong where cups are not filled with any liquid.
1. Make a shot = opponent take 1 shot

2. Make a shot, but cup falls over = opponent take 1 shot, .5 shot penalty for thrower
3. Knock over cup = .5 shot penalty for thrower
Lets play Spong instead of beer pong bro!
