Slumpkin

The act of masturbating on the toilet while squeezing out a Cleveland Steamer. AKA, the Self-Blumpkin.

Slumpkin

The act of auto-fellatio whilst in the throes of defecation.

Joey was so trashed last Friday that while he was dropping a deuce, he decided to give himself a Slumpkin, passed out, rolled forward and woke up covered in his own shit.
