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.
