Receiving fellatio while taking a shit and drinking a Raspberry Snapple Iced Tea (made from the best stuff on earth TM).
Arpy was stressed out after a hard day at the lab, so Ben gave him a raspberry kerplunk... What a pal!

A Green Day album with amazing songs such as Dominated Love Slave by Tre Cool and Christie Road. The reason the name was given is because Kerplunk is the sound a dookie makes when it lands in the toilet.
Kerplunk! 💩

this is when a guy is taking a piss while getting a rim job. as opposed to a plumpkin which is a BJ whilst taking a shit.
bob was peeing in the woods when susan came right up behind him & began eating his hairy ass out, aka a kerplunk.
