When a guy is eating out a chick while she is taking a massive shit.
"That was the best reverse blumkin ever son!"

The same as a traditional blumkin, but instead of the dude having a dump while getting his knob polished, its the lady that's is crapping on the toilet while giving oral. This is for those guys who like the role reversal where the woman is the man along with the smell of shit.
"She gave me a reverse blumkin after our dinner at the East Indian restaurant last night."

When a guy jerks off in a toilet and shits in a girls mouth. Know to be popular in Amsterdam.
The other night at Dunkin-Donuts, I paid some crack whore 5$ to allow me to preform a reverse blumkin on her in the bathroom.
