The act of getting a blow job while taking a shit on the toilet inside a Porta-Potty. Very similar to the plain BLUMPKIN. Just watch out for the blue water.

Similar to an ordinary blumpkin but in this case the girl A.C. Slater's the toilet and blows the guy as he upper decks the toilet.
Chad and his girlfriend had to shit at the same time, so to kill two birds with one stone she gave him a double blumpkin in her parents bathroom.

One who is the best at giving blumpkins, which is the act of sucking a man's penis while he is taking a poop on the toilet.

the act of receiving a blowjob while simultaneously taking a dump, peeing, and eating pizza, or maybe cake. if you accomplish this, i'm proud.

The standard blumpkin affair with a twist: instead of the usual mouth hug while taking the browns to the super bowl, she (or he if you're so inclined) dons a jack-o-lantern (preferably of the toothless persuasion) and then blumpkins you to orgasm. It's a seasonal thing - like the bj version of the shamrock shake.
It was Halloween night and I could tell magic was in the air when a jack-o-lantern was giving me head on the toilet, the old "pumpkin blumpkin"

After rob had thrownup in the stall, stephanie proceded to crawl under the stall getting throwup on herself during the process. She then gave him a sloppy blumpkin.

When receiving a blumpkin one takes it to another level and punches the sucker in the back of the skull. Rude and efficient.
"Wow, you hit her pretty hard Rick. Why'd you give her a blumpkin punch?"
"Because there's nothing more humiliating than being punched in the back of the dome while blowing a dude on the shitter."
