BUFF originally refers to the B-52 Stratofortress long-range strategic bomber. The enormous aircraft was extensively used for carpet bombing missions in Vietnam and as a first-strike or retaliatory strike nuclear weapon delivery vehicle during the cold war. The crews rarely referred to the aircraft with its real name, instead they used the acronym BUFF, for Big Ugly Fat Fucker.
The fuckers shot down two of our BUFFs last night during a carpet-bombing run. We need better flight planning!
