upper decker double deluxe blumpkin

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!

Dumpster Blumpkin

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.

The Great Blumpkin

As was foretold by Linus in It's the Great Blumpkin Charlie Brown! It is the king of all blumpkins and can only be had on Halloween night. According to Norse folklore, it is the best blowjob that you can possibly get while sitting on a toilet and taking a shit.

Rick: Yo, Sal, it was halloween last night, did the Great Blumpkin show up?
Sal: Yeah, i had like three calzones and then I wanted to take a shit but she wanted to get kinky. Let's just say The Great Blumpkin arrived on schedule
Rick: Sick
Sal: Ya, totally fuckin sick

country blumpkin

a country blumpkin is a variation of the blumpkin, where the recipient of the head giving is sitting in an outhouse instead of a toilet (and the person performing the fellatio is usually a sister or a cousin).

Cletus: "Ellie May, come out to th' shitter 'n give me a country blumpkin!"

Ellie May: "Well shit, I already gave Paw a country blumpkin! You'll have to wait 'til after supper!"

blumpkin on the spot

This is a variation to the more common term blumpkin. The major difference is that this act of receiving a blowjob while taking a shit takes places inside a port-a-potty.

I got a blumpkin on the spot from that chick at the Tom Petty concert

Blumpkinetics

The study of the physics involved in giving and receiving blumpkins. This field includes such concepts as oral/anal viscosity and drag analysis, Navier-Stokes Fluid computations, and statistical fecal scattering modeling.

I just completed my Masters of Blumpkinetics at Brown University.
