To reiterate, "Is there any other instance of an offensive term being used by a group that will not tolerate its use by members outside of the group?"
In Oz "blackfella" can get a "whitefella" into trouble. It's line ball, but sufficiently close to the precipice for wise whities to not use in public.
I'm white but, when talking with aboriginal people, take no offence at them using "whitefella" in reference to a third party. I hesitate however at using "blackfella" in the same context. Believe it or not, I've found that asking, "Is he one of your mob?" is more acceptable once we've grown comfortable with each other.
Both terms have their origins in Pidgin English, though inevitably the second half of the word was pronounced "pella", reflecting the difficulties most (all??) of the 1,000+ aboriginal languages have with the 'eff' sound.
