fanny weasel 

The ancient Mesopotamian sex act in which a small forest-dwelling mammal is placed into the anus of your wife and left there for 8 days and 8 nights until the ultimate assgasm is achieved.

Guy 1: Dude where were you last night? I told you I was having people over to watch season 2 of the O.C.

Guy 2: Yeah my bad bro. I went over to that slut Monica's house and we totally hooked up. She told me I gave her the best assgasm she's had since she last got fanny weaseled in '94.

Guy 1: Word.
