Black and Decker

Black and Decker is a sex postion for a girl who dosen't want to take her shirt off. The girl must be wearing a low cut shirt and showing alot of cleavage. Once this is complete the guy takes off all his clothes. He then has the girl sit down while he stands. After this is complete the guy puts his ass in her face and puts his penis into the breast slot provided by the shirt. Once this is done the guy titty fucks the girl up and down like he is using a black and decker drill as the girl gives his ass a rim job.
Spencer tried as hard as he could to give morgan the Black and Decker but failed.

Spencer might be the only one to actually try the Black and Decker on a girl.

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.
