Upper decker delux 

The act of sharting in public and then taking your shit pasted underwear off and disposing of it in the tank of the toilet

Man 1. Boo boo has been gone for awhile

Man 2. He's probably taking a shit

Man 1. He farted before he left so likely

Person in question....we need to leave

Later admits he put his shitty underpants in the tank of the toilet of a public setting to avoid being embrassed

Now their shit covered under pants are worse then discovering actual shit in the tank

The upper decker delux

It's the act of the man taking a dump in the tank of the toilet while the woman takes a dump in the bowl while giving the man a blowjob while a third party performs a golden shower.

Dude, last night Stacey and Dave and I did the upper decker double deluxe Blumpkin, it was gnarly!

One person sits on the toilet while the other person stands above him. The person sitting is giving a blowjob to the standing person while both are taking a shit.

I walked in the public restroom and caught my roommate and some stranger doing the upperdecker double blumpkin deluxe.
