Upper-decker Double Blumpkin

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.

Triple Decker Fluffanutter

One man sitting on the toilet the normal way while pooping. While a second man is sitting on the first man’s lap, facing the first man, pooping as-well. All while a third man jerking of the second man, while they are all looking at the second man’s penis.

European Double-Decker

Performing a European Double-Decker involves a male and female deficating in the bowl and resevoir (respectively) with the male straddling the resevoir, thus giving him access to perform cunnilingus on the female.

Brad and Angela just got back from a European Double-Decker in the bathroom. You can tell by his white mustache and brown soul patch.

She's got that Mariah decker vibe going
