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.
