A variant of whiffle ball (a variant of baseball) played with a plastic ball and bat and a cooler full of beer. The game is played like a regular baseball game with rules adapted to the number of players and the quirks of the playing field. Some rules include:
"The Beer Inning," Usually at the top of every inning, depending on the size of the beer supply.
Each batter has to hit left handed on every third at bat.
"The seventh inning blunt."
After school we're gonna go play some whiffle beer. You in?
Fuck yea I'm in.
