Several years ago, while driving from Ontario to Nova Scotia, we stopped for breakfast at some place in Vermont, New Hampshire or Maine. We were regaled by the locals in the diner blessing the recent departure of the weekend Massholes. "They come up here and act as if they own the whole state."
Haven't heard the term since--gotta' be over twenty years now. Mind you, I never met a Masshole I didn't like.
