Heydrich,
You are not the only one who knows what that means. Yes, it is a bit rude. Those of us who have been in the military have been exposed to this expression, just like a lot of other less than polite terms. Thank goodness only the acronym is being used. I do not think any rudeness was intended. Sometimes we forget (myself included) that our audience does not have the same experience as we do. It doesn't make the user a bad guy, just a little forgetful of how far this forum reaches.
