Drunk Level: Getting Started, Buzzed,Drunk , Hammered, Shit Faced

 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!
