When you unintentionally get your girlfriend's period blood in your beard, and it forms a part. (Not to be confused with a Dirty Magnum).

I just performed cunilingusand noticed blood and a part in my beard, laughed and thought "ha ha filthymoses"

Reverse Filthmosis

v. Close relative to the "Filthy Folletta" and sometime performed afterwards, A Reverse Filthmosis is performed when a drop of sweat that has beaded down a heavy set woman's ass crack and is caught by the tongue.

Dude I totally gave that huge bitch a Reverse Filthmosis.

You should have seen the look on her face when I gave her that Reverse Filthmosis.

Mom: "What did you learn in biology today?"
Boy: "Reverse Filthmosis."
