To receive a blumpkin (Getting one's cock sucked whilst taking a shit) while hanging out of a door mid-flight in a Blackhawk helicopter.
Jack was getting a Blackhawk Blumpkin at 1,500 feet when the pilot banked hard left and she blew chunks all over his chode.

After you somehow manage to convince a freak to give you a blumpkin, just as they go down, you piss in their eyes.

Where a man sitting on the toilet without pants is turned around towards the tank while a woman comes in behind his ass and sucks his dick while he shits and subjects said woman to the splash zone.

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.

I ate too much sloppy Mexican food for dinner, but my wife helped me through my pain by giving me a great speedy blumpkin.

While a man is shitting and receiving a bj another man runs in as you finish and shoves her head between his legs into the shitty water
