I use that expression all the time. I probably use a lot of southern-esque expressions, like:
Bless your little heart.
Don’t fret about it.
Rode hard and put away wet (definitely a western expression).
Finer than frog’s hair. (Ever see hair on a frog? Pretty damn fine, right?)
Down and dirty (which I’ve been told is Southern. Is it?)
Plumb – as in “just plumb stupid.” I confess to not using this one all that often.
Go hog wild.
Do go on.
Two shakes of a lamb’s tail.
And, a southern poem:
A gum chewing girl and a cud chewing cow
Are just alike yet different somewhow.
Ah, yes, I see it all now.
It’s the thoughtful look on the face of the cow.
How about you? Any southernisms you use?
