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.

Double Decker

A Double Decker is the action of one removing the top of a toilet, and proceeding to take the actual fastest shit in the top toilet, and leaving it floating like the fucking Titanic.
Double Decker are usually meant to either torment or assert dominance by defecating inside of the toilet.

My friend always asks to use the bathroom, every-time I say “ Don’t shit in the top of my toilet”.
Then he says “I’m not going to”.

Then he Double Deckers me, and I find it a week later because my bathroom develops the most malevolent smell.
