Its simple, the more people who play the better. you put in any fighting video game. everytime you lose you take a shot or a big swig of beer and take of one peice of clothing,(socks can count) then get up and pass the controller the next person.
If you playing with even # of opposite sex after you are naked. if you lose a fight the winner gets to tell the loser to do a sexual type thing to the winner or anyone esle thats playing. its better if you stay in the same room as everyone else.
