Mother Fucking Dissertation: A term coined to define the seemingly impossible, never-ending process of moving from ABD to Ph.D. with one's sanity intact. First used for the eight-year anniversary of an as-yet incomplete and undefended dissertation.

My fucking dude. This word is used instead of saying something along the lines of, "Dang player, you be spitting that game!" It's much more discrete, and just as effective.

Someone who thinks that he is cooler than he is. An MFD spends all day in the weight room usually L.A. Fitness but any other weight room is allowed as long as it has mirrors. Has no problem with self esteem and texting 12 girls at one time is not a problem as long as he has a carton of juice, is wearing some oakleys and bumping in a pickup truck
That MFD is getting huge in front of that mirror right now.
