CDMF 

Crop Dusting Mother Fucker

A person who intentionally leaves a room to fart, regardless of who is in the target room, usually to avoid stinking up their location and hide the fact that they are the person who farted.

"Oh my god that CDMF Dean did it again, it smells like he shit his pants!"
