It's the act of the man taking a dump in the tank of the toilet while the woman takes a dump in the bowl while giving the man a blowjob while a third party performs a golden shower.

The unspoken act of a female performing an upper decker, whilst a male counterpart carries out a defecation in the lower (relative to aforementioned upper deck) deck, whilst eating out the aforementioned female.
Gary and Bruce were both really excited to partake in the sensual act of a Double Upper Decker Double Reverse Blumpkin, but neither one had eaten a large enough meal to carry out the act.

One participant is sitting on the upper deck of a Toto Toilet while your partner is sitting on the lower deck; with the seat warmer on and the water blasting against their genitals. The upper decker is receiving Fellatio while both parties are passing a Cleveland steamer.
Guy 1: Gawd! Julia is such a basic bitch, i cannot stand her.
Guy 2: Sure, but at least her parents are rich enough to afford a Toto Toilet.
Guy 1: So?
Guy 2: She totally gave me a Steamy Upper Decker, Double wet Blumpkin
Guy 1: Legendary!

The act of, in this very exact particular order: finding a sexual partner and take them to eat a substantial amount of Taco Bell with you. When you both inevitably need to take a diarrhea shit, do it at the same time, with the submissive sitting on the bowl and the dominant sitting on the opened top tank. During the shit, the submissive will perform oral sex on the dominant. When the dominant finishes on the submissive’s face, they must punch the submissive in the nose to create a mixed fluid of blood and ejaculate on their face. Once both parties complete their shit. They will perform a reverse sixty nine on each other until both anuses are clean. Then the dominant must lick the submissive’s face clean.
Man 1: hey bro, why did you break up with your girlfriend? She seemed really nice.
Man 2: nah bro, she was so selfish, she wouldn’t even do a kentucky jelly doighnut upper decker double blumpkin supreme with me!
Man 1: oh man, I didn’t know that, what a selfish bitch!
Man 2: nah bro, she was so selfish, she wouldn’t even do a kentucky jelly doighnut upper decker double blumpkin supreme with me!
Man 1: oh man, I didn’t know that, what a selfish bitch!

A dude sits atop the toilet tank and craps in it, facing forward. A woman (or man, I guess...) sits on the toilet backwards and also crals as s/he performs oral sex on the guy seated atop the tank.
What were you two doing in the bathroom so long?
I expelled every fluid imaginable thanks to getting an upper-decker double blumpkin.
