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.

When five men have intercourse with five seperate partners, or perform dual penetration on a shared set of partners with one "odd man out", using one shared latex rubber glove as a prophylactic. The term is derived from the Mattel brand game, Kerplunk, which also involves many rods crossing, and balls dropping.
This weekend, Tom, Dick, Harry, Barry and I kerplunked with Susie, Mary, Annie, Liz, and Frank.
