Upper Dutch Blumkin 

the combination of an

Upper Decker (Pooping in the tank)
Dutch Oven (Farting - then pulling the covers over your partner's head)
and a Blumkin (Getting a blowjob while taking a dump)

In other words - Pooping in the tank while getting a blowjob with a towel over the blowjob giver's head

this is a class move - only performed at major burns (like Burning Man) or in Northern Virginia to settle a blood feud

I thought it was just an upper decker - but the fucker left a picture of my Mom giving him an upper dutch blumkin

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.

blumkin 

The term BLumkin is when a man is sitting on the toilet taking a shit. And has his woman come in and give him head during the act of shitting.

"Bitch get your ass in here and give me a blumkin!"

The action of a person receiving a blowjob and getting their ass hole eaten out at the same time while taking a poop.

Blumkinuku 

Getting a blow job while taking a shit and completing your Suduku. (For best results have the Suduku on a clip board resting on her head)

The suduku I was working on was too difficult so I decided to have my wife give me a blumkinuku while I figured it out.
