Dean and the Nighthawk's definitions
Somewhat analagous to the blumpkin, this is when a guy, while standing upright, is receiving oral sex from someone sitting on the toilet taking a dump.
Yo, my girl and I had Mexican for dinner last night, and when we came home, she gave me the fattest dumpkin ever.
