Double Decker Home Wrecker 

A totally rad version of an Upper Decker. This act usually requires two fecal filled individuals. First open up the top part of the recipients toilet and pinch a few hefty loaves inside. The next step is to shit in the toilet bowl. first a layer of toilet paper, then crap on top, then another layer of toilet paper so its sure to leave a nice clog. The recipient will try to flush the mess down the toilet but be pleasantly surprised with a brown whirlpool of shit. even if they try to plunge it, more shit water will come to the scene.

A) Hey, them reggins are having a party!

B) Are you thinking what I'm thinking?

A&B) DOUBLE DECKER HOME WRECKER!!!!!
