Something I love about the Appalachian South, aside from pimento cheese and red velvet cake, is the Southern sense of humor. Done well, it's a self-deprecating, sly kind of humor, directed at those who may be a bit too full of themselves--often Yankees--and it's very funny. I also love the absurd use of words. For those who don't attend church, it's that "they ain't too churchified." The process of jerryrigging a machine or process is "hillbillying it." Yes is "yeppy." There's also a lot of "fixin,'" as in "I'm fixin' to go to the store," or "I'm fixin' to git my can of whup ass."
I'm fixin' to keep a list of my favorites.
