kerplunk 

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!

A great Green Day album. It ties in with the other cd "dookie" because, as lead singer Billie Joe says, "When you take a s--t in the toilet, that's the sound it makes is kerplunk."

I picked up the Kerplunk album on vinyl yesterday at the music store.

A shit that is a piece of art, ie.

A shit that has to be admired after taking.
