Filthy Roger 

If you cut yourself, either on accident or on purpose, then grab your fuck muppet and bang one out really quick before the blood quits dripping, and right before you nut, smear blood across her upper lip, then cover it with jizz, you've given her a Filthy Roger. Bonus for extra running and dripping.

Me: "FUCK! I cut my finger!"

Fuck Muppet: "Are you ok?"

Me: *Crazy laugh* "Come here, I'm gonna be fucking FAMOUS when I coin the phrase 'Filthy Roger' on Urbandictionary.com"

Filthy Robertson 

The act of gaining revenge on a cheating girlfriend by cumming on the pillow her new lover now sleeps on in her bed so the jerk can roll about in your jizz while he sleeps with your former girlfriend.

"I can't believe that bitch lied about fucking that loser. No worries though, I got mine with a Filthy Robertson!"
