Upper Decker Blumpkin AC Slater 

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!

blumpkin on the spot

This is a variation to the more common term blumpkin. The major difference is that this act of receiving a blowjob while taking a shit takes places inside a port-a-potty.

I got a blumpkin on the spot from that chick at the Tom Petty concert

Self Serve Blumpkin 

Similar to a Blumpkin except there is no second party involved. The self serve consists of jerking off while taking a dump. The self serve happens much more regularly because you do not have convince a slore to blow you when taking a crap.

Mike muth was on the prowl for a blumpkin but wasn't coming up with a suitable candidate, therefore he had to resort to the classic self serve blumpkin.
