upperdecker

When you shit in someone’s toilet tank. To pull one at a lame party, first eat everything there that doesn’t agree with you. Then go into the bathroom, remove the lid from the toilet, squat over the tank, and release the explosive diarrhea that has surely built up by now. When you are finished, the water in the tank should be brown, and have dozens of lumps of shit in it. Then wipe your ass, putting the used toilet paper in the tank, replace the lid, and leave the party, or stick around to watch the fireworks.

This party is dumb, i’m gonna drop a mad upperdecker on this place.

Upperdecker double blumpkin deluxe

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.
