double-decker 

Double-decker, or to pull a double-decker, is when a girl is having sex with two men, whereas one is thrusting his manhood in her ass, and the other man is penetrating her vagina. Often done to completely dominate the woman, and/or a symbol of the friendship between two men.

Double Decker 

To leave an Upper Decker in the toilet tank, and to leave a Floater in the bowl. This can either be a two-man job, or performed by a single person who breaks his payload into two segments. The result is that the water in the bowl will be brown, and the water that comes from the tank during a flush will also be brown.

An upper decker wasn't enough for that place, so for good measure I left a double decker.

double decker 

When you take a deuce in the upper tank of the toilet. Leaving the owners to believe the toilet is broken, since the water comes out brown and pieces of fieces. This continues until someone either scoops it out of the upper tank or it dissolves.

Usually happens at mad crazy house parties or when someone mad dogs another person and allows them to use their bathroom.
