Snumpkin 

You sit down on the toilet, ready to receive your average, run-of-the-mill blumpkin. But wait, why are your arms so cold? You put on your Snuggie and call your bitch into the bathroom, proceeding to cover her body with the rest of the Snuggie. Dutch oven blumpkin, bitch.

Derp: "Duuude, my girlfriend gave me a snumpkin last night!"
Derpor: "No waaay, duuude, that's like a dutch oven blumpkin!"

snumpkin 

the act of serving up a tenderizing blumpkin and put a finishing touch of a luscious snowball on it.

My girlfriend serves up the meanest snumpkin, but then comes the after-taste. (No..., Dignity, don't run away from me.)

Shumpkin 

As opposed to the classic blumpkin where you are receiving head while shitting, she is shitting while you receive a blowjob!

Schuyler: yo this girl just sucked my cock while she was shitting!
Oscar: YOU RECEIVED A SHUMPKIN!!!
Schuyler: YEA and I blew my load in her hair

Swumpkin 

A swumpkin is the offspring of a Frankenstein swede and a pumpkin. It is about 3/8 pumpkin, 3/8 swede and 2/8 Frankenhuman.

"Hey. I'm a swumpkin!" said the pumpkin-swede-Frankenhuman baby.
