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!
