MFD
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.
