So on company, talking to pilots in the same company, the guys call themselves "the 11" or the "the 8"? Thats your definition of a ****** is it?
It is a shorthand way to communicate a lot of information.
It communicates the departure point and the destination, the planned ETA and aircraft type all without having to say it. You might work for an airline that has only one flight a day over the Pacific or anywhere else but the QF guys (at the moment anyway) don't.
I think I know who the ****** is here.
