When you go to the county fair with your girl and get hammered and she gets horny so she blows you while you’re sitting on the port-a-John.

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.

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.
