This is not really a game, but beautifully referred to as "a call to action, a frenzied rally for a cause held dear by the participants." Supplies: people eager to drink themselves silly, and a keg of beer, brand irrelevant.

At some time during the course of a party, particularly at a low point, maybe near the end of an evening, all it takes is for someone to shout, "Kill the Keg!" Participation is mandatory. Everyone heads to the keg, and doesn't stop drinking until the keg is done, emptied, drained, dry, KILLED!
