Dirty Fester 

The Dirty Fester is when you fist your roommate and then leave the room mid nut and piss in his trash can.

“My roommate was in the middle of doing homework so I went in his room and gave him a dirty fester.”

Like a Dirty Sanchez only you stick your finger in your own ass so that she does not see it coming.

I was going to attempt the Dirty Sanchez but I think she was suspicious, so thinking on my toes, I busted out with the Dirty Foster instead.

Dirty Foster

When you fuck an Alaskan Hooker while rubbing whale lard on her pussy, using it as lube.

"During my vacation in Alaska I gave this chick the ol' Dirty Foster."
