Double Decker House Wrecker Blumkin AC Slater

Carefully removing the toilet tank cover, dropping a deuce in the upper tank while receiving a blojob from a partner that is taking the browns to the superbowl and positioned backwards on the seat as if AC Slater from 'Saved By the Bell.' After all purging , liberally wipe and if necessary add extra toilet paper to the lower tank to ensure a severe toilet clog.

I caught Hercules bull riding my girlfriend so before I left I gave him the good ole double decker house wrecker blumkin ac slater.

Black & Decker pecker wrecker

An African American prostitute with braces

This black hooker I picked up once started to blow me and it killed. I later realized she was a Black & Decker pecker wrecker.

Double Decker

The act of sitting in ones lap while he or she is sitting on the toilet. The individual on bottom produces excrement into the bowl of the toilet while the individual on top produces excrement between the bottom individual's legs thereby creating the "upper" portion of the deck.

*Often confused with an UPPER DECKER, in which one individual produces excrement into the upper tank of the toilet.*

*See also: Upper Double Decker

Roommates Ezekiel and Jebediah both consumed too many matzah balls and were locked in a heated stand-off over who may use the toilet first. They decided to compromise and perform a DOUBLE DECKER.
