booty bash is a wet shirt contest without the wetness or the tshirts. typically a bunch of gross skanks (some beer guts included) in booty shorts, with a hottie or two mixed in. Often times there are a bunch of old bar heads in the front row trying to cop a feel. look up "pro hos", or "surf groupies" and youll get an idea. regardless the drink specials are sweet. And if drinking cheap beer requires judging an ass contest I'm in.
