"Buff" means you're over 160+lbs who is cut and actually has muscle that shows. If you are under that weight and only have a six pack you are not qualified to be called buff. In fact you are skinny. So delete those pics of you lifting up your shirt.
Damn Jake is getting buff! Did you see his traps and triceps?! You can see them more defined! Unlike Esteban who is just skinny.

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.
