My favorite mysterious Bostonism was "Mistagavodabody" (Mystic Ave. Auto Body).
Buff, that accent sounded pretty awful to me, and I have no idea what North Carolingians talk like.
Well, I have no accent, to the point where people always guess I'm from a place where they don't know what people sound like - Iowa is one I get. They're just flailing. I grew up in a faceless suburb surrounded by Yankees.
The most pleasing North Carolinian accent to the ear is the one spoken by rich families from the Piedmont.
If they were to say "Don't cry, dry your eye," it would sound a bit like "Don't crah, drah your ayh."
It's impossible to replicate here, but it sounds really cultured and interesting.
There are, I hear tell, Southern accents that are less pleasing to the ear.
