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.

Polar decker

The act of defecating directly in someone's freezer. The result of this poopsicle predicament is whether to chip away at a frozen browntain or unplug the unit and deep clean because everyone knows you're the germophobe you know you are.

Found out Lou slept with my girlfriend and never told me so I left him a polar decker while he was sleeping so it froze solid before he found it.

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.

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.

“My friend Roberto is coming over Saturday night, would you join us to complete our Triple Decker Fluffanutter?”
