This is a variation to the more common term blumpkin. The major difference is that this act of receiving a blowjob while taking a shit takes places inside a port-a-potty.

A guy gets his dick sucked while taking a shit. Its a race against the cock to see if he can shit before he cums!

This is the act of giving/receiving a blumpkin, from a girl or a boy, while the giver is blowing the receiver the giver must vomit all over the receivers cock and lap, induced by choking on the receivers cock. Typically after an Oriental Blumpkin commences the fellating party puts their hand in front of their mouth and makes a racially stereo-typical Asian laugh.

The act of getting a blow job while taking a shit on the toilet inside a Porta-Potty. Very similar to the plain BLUMPKIN. Just watch out for the blue water.

When a couple is doing a sitting 69, the man takes a shit and the woman is on her period. (Obvious blumpkin + red wings reference)
That is the nastiest girl I know. She did a Detroit Blumpkin. Hell, and her boyfriend is almost as bad.

Similar to an ordinary blumpkin but in this case the girl A.C. Slater's the toilet and blows the guy as he upper decks the toilet.
Chad and his girlfriend had to shit at the same time, so to kill two birds with one stone she gave him a double blumpkin in her parents bathroom.
