Upper Decker

Step 1) Make sure nobody's around.

Step 2) Quietly open the lid of the upper-section of the victim's toilet.

Step 3) Quietly place the lid down on the floor.

Step 4) Then take a nice shit in the upper-section of the toilet without letting anybody hear you.

Step 5) Wipe your ass.

Step 6) Place the soiled toilet paper in the upper-section of the toilet or in a drawer or magazine.

Step 7) Slowly lift the lid off the floor with your fingers under it and carefully bring it over to the toilet.

Step 8) Here's the hard part; with your fingers under the lid
slowly place the lid on the toilet. No false moves or you're screwed.

Step 9) Leave and don't let anybody see you. Just bail as quickly as possible.

Step 10) Mission accomplished.

Plumber: It looks like you have feces in your toilet's tank.

Victim: It must have been an upper decker.

Plumber: Yeah right. Its already clear that you're stupid enough to shit in there!

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 Deck Deluxe

Where you do a standard Upper Decker (take a dump into the Upper toilet tank), BUT you have disconnected the chain beforehand so that some poor sap has to reach into your poop soup to even flush it.

That bitch pissed me off so bad, I got her back with a full upper decker deluxe so she'd have full shit hands after fixing it.
