The act of receiving head while taking a masssive dump, but when you get ready to cum, you tell her to close her eyes and open her mouth. Then you do a 180 and shit in her mouth.
As Stephanie thought she was giving Jacob a regular Blumpkin, he told her to close her eyes and he gave her a Black-Hole Blumpkin.

My girl made me go on a diet so I can only receive gluten-free blumpkins.
Since I’ve started my diet, I’ve lost 10 pounds off of gluten-free blumpkins.

Recieving a blumpkin while taking an upperdecker with the person performing the blumpkin turned around backwards on the toilet sucking you off and simulaneously taking a shit.
That was some fucked up shit last night, I can't believe your mom gave me a reverse upperdecker blumpkin.

When a man has anal sex with a woman, fecal matters get on his dick, and the woman then gives him a blow job with the fecal matter still on his dick.
"Last night I was pounding my girl in the ass when I felt something warm on my dick. She shit on my dick, so I made her give me a reverse blumpkin to clean it up."
