I live in the middle of the mountains of North Carolina, Marshall. This county is notorious for having the most hillbillies of any county in the state.
And I lived in central Georgia for 22 years before I came up here. Both places, Deep South. But different.
Down in central Georgia, the word for second person plural is, of course, "Y'all."

But up here in hillbillyland, the expression is "you'uns." Also they have a nasal twang to the speech up here in the mountains.
