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.

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.

Greek Upper Decker

The art of sneaking into a frat party for the purpose of taking the most massive grueling shit in the upper tank of the frat house's toilet. That way when they wake up to clean the place in the morning, they are greeted with the most fowl awesomeness that only frat boys deserve.

Dude, I totally dropped a Greek Upper Decker in ZBT this past thursday.

Sweet. Those guys are dicks. You deserve a trophy man!
