horribly disgusting beer equivalent of piss water that's most widely known as milwaukee's best light. incredibly cheap and only drinkable when absolutely fucking tanked. also a source of alcoholism among college students.
Guy 1: Grab me a beer.
Guy 2: Ok here's a beast light...
Guy 1: Fuck your stupid ass piss water!
