Best played in urinals, battle piss is similar to battle shits. Two, three, or even four contenders load up their bladders, and release their powerful streams against the back of the urinal. whoever pisses the loudest, whether a player vote, or judge vote, wins.
Me and jimmy played battle piss, but his stream was so loud, people outside the bathroom heard it.
