In general terms, a Babst is a Pabst that wants to be a Pabst, but it really isn't a Pabst, it's a Babst. A Babst is created by finding stray cans with beer still in them, cans that were forgotten on a table or shelf by someone, and combining the portions to fill a can. This is done throughout the party. The Babst cans are then put in the fridge, where they sit until the newer beer is consumed. The Babst is the potentially wasted beer that you break out at the end of a party.
Dude, don't worry, the beer isn't really gone. We still have about 6 cans of Babst on the top shelf, remember?
