jersey upper decker

Same as the standard upper decker except you eat a 20-pack of White Castles first and then take the massive dump in the tank. when the next poor slob flushes, the smell from the dirty water will cause an uncontrollable craving for White Castles.

When my ass was about to explode from that 20-pack of castles I ate, I gave marco's toilet a jersey upper decker.

Its is derived from The Teenage Mutant Ninja Turtles(Kowabonga which is awesome) and the drill company Double Decker add it with the word collision(intercourse) and turtle wax(symbolizes wetness. words that are ordinary alone but together mean something totally different
