|Game is best with 6-8 players.
Each player sits in a circle with their cup in front of them. Players take turns in any pre-determined order.
One player will try to bounce a quarter into another's cup. The player can pick anyone's cup to try he wishes. If the player gets the quarter into his victim's cup, that person must "talk dirty" to him (ex. 'I want your wang big boy' or something similar) to him/her. If the person hesitates, he/she must chug their beer.
The only strict rule is that after a person has drank, the next player is not allowed to attack the person that drank. After one other person's turn has gone, however, that person is fair game. This is done so no one can gang up on anyone.
This is a good game to play with a girl you might be interested in ;)
