upper blumkin 

When you pinch a loaf in the tank (upper deck) of a toilet, commonly as a prank, while getting a blowjob.

My girlfriend and I upper blumkin'ed the club bathroom to save time.

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

Upper Blumpkin 

Doing an Upper Deck( the act of pooping in the top part of the toilet ) and receiving a Blumpkin (getting head while you are taking a poop on the toilet ). The result of these 2 combined is an Upper Blumpkin .

Matt: “ Hey so last night , Kim gave me an Upper Blumpkin in the bathroom at my Mom’s. “
Kenny: “ Wow , that Kim is one sick Ho. Bet your mom was pissed after you left .”

Double Upper Blumpkin 

A slight twist on the original blumpkin.

The double upper involves a male taking an upper decker while a female is taking a dump in the main bowl of the toilet while facing backwards. While all this is happening she is blowing him.

My buddy and his girl would have a few drinks after a night of eating hot wings. When they got home they were both so horny and had to shit so bad that it would inevitably turn into a double upper blumpkin.

Upper Blumpkin 

The act of taking a shit in the top part of the toilet while a girl is giving you head at the same time.

Last night my girlfriend was so drunk and she was pissing me off and she surprisingly let me pull off an Upper Blumpkin

Upper Blumpkin 

Sitting on a toilet AC Slater style while defecating, and performing fellatio on an individual in the act of upper decking the same toilet.

It sounded like a good idea last night, but we spent all morning cleaning the tank after trying out the upper blumpkin.
