"Dude, I drove through West Virginia one time and hooked up with this hot mountain chick and she gave me a country blumpkin behind her parent's shack. It was messy but awesome!"

Ultimate Blumpkin 

To get a bj while taking a dump and eating lobster at the same time.

I went over to legal seafood and got an ultimate blumpkin in the bathroom.

Street Blumpkin 

The act of giving or receiving a blumpkin while on the street. Subject A proceeds to defecate in a street, sidewalk, or alleyway. Subject B performs fellatio on Subject A during the defecation process.

The homeless guy was already taking a dump in the alley; I thought I would be charitable and give him a Street Blumpkin.

Perpendicular Blumpkin 

A male (the receiver) sits as if to straddle the toilet, then reclines backward so that his head rests on another chair and his body is parallel to the floor. The other party, or giver, handstands on the toilet seat so that their body is perpendicular to the receiver's body while facing towards the receiver's feet, then proceeds to fellate the receiver while he takes a shit. Less skilled practitioners may allow the giver to prop his/her legs against the wall for added stability; it is to be noted, however, that this reduces the range of fellating motion.

I decided to become a gymnastics instructor so that I could receive perpendicular blumpkins whenever I had a hankering.
