F.D. 

A degree earned after a Master's Degree. F.D.'s can only be earned through multiple lessons on the internet. Though this degree is often used to insult one's ability in a certain subject.

F.D. does not stand for anything besides F Degree.

Dr. Smurf has a F.D. in SHIT. Thus, he must know a lot on the subject of SHIT.
