Nickname for the US Air Force B-52
strategic bomber, referred to as a "Big Ugly Fat Fellow" or "Big Ugly
Fat Fucker".
Considered a term of endearment when used by aviation types.
The NVA types in Hanoi were a bunch of cocky bastards until Linebacker II (major
Vietnam War bomber campaign in December 1972). The sight of all those BUFFs
rattling their windows
on a daily basis was enough to tighten their sphincters good.
