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

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!"

blumpkinschplatt 

A blumpkinschplatt is considered achieved when a girl vomits as a reaction to male orgasm whilest the male is seated on a toilet, shitting.

Note the difference between this act and a regular blumpkin. A blumpkin could be considered performed when a girl quickly puts her tounge on the tip, whereas a blumpkinschplatt is proof of it's own sexual satisfaction. Blumpkinschplatt is visceral and undoubtedly sexual whereas blumpkins are more abstract and humorous.

The redheaded girl from around the way performed blumpkinschplatts regularly due to her unusual upbringing.

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.

blumpkinsneeze

The blumpkinsneeze is the rare act of receiving a blumpkin and simultaneously sneezing.

While Kal was receiving a standard blumpkin he needed to sneeze. At the point of sneezing he simultaneously shat and orgasimed, thus achiving the blumpkinsneeze... aka complete nivarna.
