The combination of the double blumpkin supreme, the upper decker, the pterodactyl, and the eiffel tower
Tom: Dude, I saw the nastiest thing, this chick was doing the "double blumpkin upper decker dactyl tower" at that party on Saturday night.
Ted: Wow she must be a freak!
Tom: Yeah, I almost puked!
It's the act of the man taking a dump in the tank of the toilet while the woman takes a dump in the bowl while giving the man a blowjob while a third party performs a golden shower.
Dude, last night Stacey and Dave and I did the upper decker double deluxe Blumpkin, it was gnarly!
Just like any variation of the word blumpkin, this sensuous act occurs between two people who are in love with each other. A gentleman should climb into a dumpster, preferably behind a grocery store or fast food restaurant, begin shitting (pants are optional, but your ding dong must at least hang out the zipper). Then a close friend or whore will climb into the dumpster and begin to slob on the shitter's knob while he is pushing out all those juicy feces.
I was constipated after I ate at Checkers on Lewis Street, so, I walked in Blockbuster, but they wouldn't let me poo. Thankfully I stumbled across Zack's sister and a girl with the exact same name. I informed them of my condition, and they offered a Dumpster Blumpkin. So, that's how I spent my afternoon,between Checkers and Blockbuster, Dumpster Blumkining two ladies with the same name.
