A dialect word from extreme western Massachusetts and upstate New York, prevalent mostly among those born between 1935 and 1955. Seems to defy definition, but having the same weight as such words as "asshole", "cocksucker", "motherfucker", perhaps even a bit more derogatory.
A regional insult used fairly commonly in parts of New England, including Maine, with a meaning similar to asshole. Touchhole, however, is more likely to be used in a light-hearted way and is also more acceptable in public places.
