[Porterville]

I believe that, he is a pompous North East Quadrant snobby SOB, but.. he isn't a slimy nut bag... instead he is a slimy erudite (that is unless he is retarded).

" instead he is a slimy erudite (that is unless he is retarded)."

Let's get this straight.
On Cape Cod and in polite society it's retodded (as in "cod").
North of Boston and in less polite society it's retahded (as in "gonad")

Common usage in the northeast would be as follows:
"Don't be an effing retahd!"
