Generally referred to by urban New Yorkers as "upstaters", and by southerners as "yankees". Neither of these groups actually has a clue as to who or what ANYBODY is, if they live over 150 miles away from themselves, since they have never been, nor will they ever even attempt to go that far from their own familiar territory because it would be too much like getting out of their comfort zones.
