blumpkindred spirit 

A "new friend" found while cruising for sex in a public men's room. The new friend will perform a special sex act (a blumpkin) without even making the recipient get off the toilet.

Repugnican Senator Larry Craig sat down on the crapper and assumed his usual wide stance. He moved his foot toward the next stall thinking the guy next door might want a blowjob while he was taking a dump. He soon realized the guy was an undercover cop, not a blumpkindred spirit.

Blumpkinator

The action of taking a dump, while eating a Wendys* Baconator and getting your dick sucked. Enjoyed usually on sunny days, either inside a home or porta potty.

Yesterday, while receiving a blumpkin, Tom threw Fred a baconator and the blumpkinator was born.

Blumpkining 

The act of doing a blumpkin (see blumpkin: “ the act of performing fellatio whilst the recipient is defecating in a toilet.” )

" I was blumpkining all night" ( which means he spent all night on the toilet whilst getting his cock sucked)

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.

bumpkin butt 

A woman's saggy butt that developes after having kids and loosing some weight. Resembling a pumpkin that has melted and sagged after sitting on the porch too long after Halloween.

Man, Aubri used to be hot in high school, but now that she has had kids she has bumpkin butt.
