dirty dunce
After you do sexual work with a one night stand "hobag", (this must be done at his or her home), go to the corner of his or her room, take a dump, wipe your ass with his or her underwear, leave the underwear next to the victim, and leave.
Dude, I ended up bangin that ho last night. I had to poop when I was done, so I dirty dunced the pig.
