Ever notice -- when Southerners want to emphasize a thing, they repeat it?
Examples:
A shirt is not just white, it is white-white.
A couple of days off is a vacation, a week off with a great destination is a vacation-vacation.
Painfully childlike behavior from an adult is not just childish, it is juvenile, juvenile, juvenile.
Once I started to notice this, I heard it often. And, it never ceases to make me smile!
