take 10 plastic cups per team, 2 teams, one ping pong table, 2 beers per team.
put cups into triangle 1,2,3,4 with 1 in front and stagger back towards your team. fill cups with 2 beers per 10 cups. one team takes ping pong ball and tosses it at the other teams cups trying to make it in. if the ball goes in the cup then the team that cup belonged to has to drink it. uh im not sure how well this is going accross its better to play along a couple rounds, get smashed and become a natural
