A drinking game combining flip cup and beer pong that theoretically gets you so wasted that you can't get it up, hence it's name.

It starts with four cups lined up in a straight line on each corner of the table filled 1/4 way with beer. There are two people per team and they stand on opposite sides of the table so that they can shoot into each other's four cups. The first two people shoot. If someone gets a cup in, the person has to drink the cup and then flip it before he or she can shoot again. First team to get it in all four cups and flip them, wins.
