Grit Dog,
If by pompous and/or self-righteous you mean those that refuse to think of lot-docking and black-topping as boondocking instead of dry camping, then you could well be correct. People have gotten away from the old fashion thinking of "words have meanings" if favor of "any word means what I want it to and if you don't understand it's your fault".
Recently someone asked me if there was anyplace to boondock near where we live and I told him there was not. He said he was surprised that there were no Walmart or other. To which I replied that there were plenty of places they could over-night-park for free, but those sure were not boondocks.
If someone has a different definition, he is welcome to it but he should have no expectation of his private meaning being universally understood.
