The original loading of these terms was almost undoubtedly obscene, possibly referring to the scrotum, but in their current usage they have become almost completely sanitized.
A program called Lexiphage on the old MIT AI PDP-10 would draw on a selected victim's bitmapped terminal the words "THE BAG" in ornate letters, and then a pair of jaws biting pieces of it off. This is the first and to date only known example of a program *intended* to be a bagbiter.
