mf 

This is a title, used on the Miles Davis listserv, as either "Miles fan", or "mother fucker", one of Miles favorite and frequently used discriptive terms.
One is never specific about which meaning is intended when using it. That is an important part of the usage.

borrowed from a recent list post:
"gotta go!!!!
today-sunday-
herbie and wayne, ooh yeah!!
i'll let y'all know...be good and
happy father's day to all you mf's."

Used most often in scientific and university context, surreptitiously.

I don't give one mF about fashion.
