Big. Ugly. Fat. Fellow.

It is a term used by the USA military given to planes no longer in commission. These planes are used for scrape, going to be scraped,
being parted out, or in the process of being parted out.
Military Officer: Look at that buff, there is nothing left in the plane.
Recruit: Better take it to the scrape yard.

Sorta like the term D.U.F.F, meaning designated ugly fat friend, the word B.U.F.F means, black ugly fat friend.
Girl 1: Hey do you want to hang out later?
Girl 2: Yeah! Make sure you call Lisa, shes our B.U.F.F.
Girl 1: Oh, good call, I will see you girls later.

a cop that loves his job a bit too much.
sgt - aren't you supposed to be on meal?
cop - i was going, but this guy had excessively loud music coming from his car, so i threw out my whopper to write him a summons.
sgt - ...you fucking loser, stop being such a damn buff before people flip your locker.

Big Ugly Fat Fuck. The affectionate nickname pilots gave to the Boeing B-52 Stratofortress. Derived from its sheer size (159 feet long, 185 foot wingspan), and the fact that it is ungainly in appearance on the ramp, due to it's 8 engines and bicycle landing gear.
The B-52 "BUFF" is shown many times in the movie Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb, and flew the world's longest combat sortie in 1991 in support of Operation Desert Storm, launching AGM-86 cruise missiles against high priority Iraqi targets.
