Rumpel Blumpkin 

Is derived from "Blumpkin" where you receive fellatio while defacating. However, a Rumpel Blumpkin is when you receive fellatio in a the same bathroom stall or toilet as somebody who is defacating.

I took this chick to the bathroom, but Joey was already taking a dump, so she straight gave me a Rumpel Blumpkin while he watched.

Getting a blumpkin while taking a die-reah and then back-flip kicking the shit out the bitch like Charlie from Street Fighter Alpha so she hits the ceiling. 10 more points if she lands in the toilet. Don't forget to scream "KUNGFU!!!!"

Some ho-bag was ho-baggin me while giving me a blumpkin, so I switched up and made it a rumple blumpkin.

The act of Blumpkins (taking a doodie while receiving a blowjob) from your grandma.

"Grandma, we both know that I finishing shitting a long time ago, but in order for this to be Rumpleblumpkins, you need to stop watching and give me a blow job, NOW."
