- We had a term in the military for a soldier who was not a good Battle Buddy. He was a "Blue Falcon." That rather odd name is an attempt to clean up a much more graphic term. The initials for Blue Falco, "BF", were originally the first letters of a term I'll refrain from printing here. Let's just say that the "B" stood for "Buddy" and the "F" stood for a classic word of profanity. A BF was someone who screwed his buddies. We just called them Blue Falcons.

- To them, he's a Blue Falcon, a derogatory euphemism for "buddy-fucker." Blue Falcons are great soldiers when the commander's watching. But they'll screw you in a heartbeat when nobody else is around.
