Upper Decker Demolator

The act of filling the top reservoir of someones toilet with liquid feces. Preferably, after the mass consumption of spicy foods such as vindaloo or chili.

Oh my god, an Upper Decker Demolator! I keep flushing and it keeps coming back!! Ok, you keep flushing, I'm going for more bleach. And some mints, in case you have to siphon it out...

upper decker

Besides the common definition... A behemoth, often coiling, mass of stool that grows and grows until finally reaching above the water level of a toilet bowl. Known to be associated with binge eating. Kind of like one of those underwater volcanoes that breaks the ocean surface.

I had the munchies so bad all weekend, btw do you have a plunger I took an upper decker in your shitter and it's backed up.

Upper Decker Double Blumpkin

The very intimate act in which the male lover delicately removes the top cover on the porcelain tank of a toilet. Next he will mount the the tank and begin to defecate. Now the female lover gently sits on the toilet seat facing her male partner. The act begins when she also compenses to defecate while orally accepting his genitalia.

I knew she was the ONE when she pulled me into the hotel bathroom and introduced me the amazing upper decker double blumpkin.

Upper decker dry docker

its where you turn off the water on the toilet before someone takes a poop and you take a diarrhea in the upper water chamber. Then when a person sits down to take a poo, it lands on the porcelain and sticks, then when they go to flush it shoots diarrhea out. causing a horrible situation

Man that was funny when billy gave her the old “Upper decker dry docker”, her trailer smelled like feces for months.
