A variation of the blumpkin where one gives oral sex whilst evacuating their bowels, thus utilizing both alpha and omega of the ailimentary canal simultaneously.

Or in laymans terms, when one sucks a cock at the same time they are also beaming Schatner off the Enterprise....the sucker is the crapper.

Note: The money shot should occur at the precise moment of final fecal release, thus synchronizing anal closure with ejaculation.
While his wife was taking her weekly shit, Ulysses whipped out his cock and got a BJ from her at the same time. Ahhhhhh...... she was the only woman he ever knew that would give a reverse blumpkin.

In the 16 hour traffic jam before the Phish show, we observed a woman run into the woods with her boyfriend. The two perched on the steep banking, not hardly out of sight of the headlights, when she pulled down her dress, revealed her stark white ass, and assumed the squatting position. She was squatting too long to merely urinate and was obviously laying serious cable. To our amazement, her head dissappeared into the mans crotch!! Social morays be damned, this was a reverse blumpkin, and the symphony of car horns signalled the glee and elation of the stunned masses.
