This act requires both a male and female to perform. A male takes a crap in the upper tank of the toilet while performing a delicate balancing act, and getting his cock sucked, as the female takes a crap on the toilet facing the wrong direction. Much like how AC Slater sits in a chair when he's at the Maxx.
I got my girlfriend so drunk that I was actually able to convince her to perform the Upper Decker Blumpkin AC Slater with me while my buddy hid in the closet and video taped the performance!

The art of recieving a blowjob from a woman while she is shitting in the bowl of a toilet and you are taking a shit in the tank/cistern of the same toilet at the same time.
