A game where one climbs on top of the stall walls in a public restroom and takes a shit while aiming for the toilet below. Named for the sound a turd makes after falling 6 feet into a toilet.
Don't use the middle stall... I tried a kerplunk in there earlier and totally missed!

Get the kerplunk mug.
