Double Decker

Similar to the Upper Decker, the Double Decker involves taking a shit in the victim’s toilet, not flushing, then repeating the process in the tank. The end result is the unsuspecting victim flushing the lone turd, only to be accosted by a stream of liquid feces into the bowl. This is far beyond an innocent prank, be sure the victim deserves it, as there’s no going back.

Allen was house-sitting for Sam and had a party at his house...he was only caught because somebody left a Double Decker in Sam’s toilet.

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.
