The good folks at www.alphadictionary.com are offering a "Glossary of Quaint Southernisms." I've lived in the South (NC) for more than 20 years, but not having been born here, I still don't feel like an expert on the dialect! Some of these I recognize, like "fixin" and "catty-corner" and "conniption" (one of my favorites!), but others I've never heard of ("chinchy"?).
I like what they say in their intro., as I get mad when people judge others unfairly, based on an accent:
"Your accent has nothing at all to do with intelligence or knowledge of the rules of grammar. It is simply a regional dialect and dialects are equally grammatical; they are simply slight variations in the grammar of a given language that characterize the various regions where that language is spoken."
