Here are some Southernisms of my own.
First, two that I recall from a colleague I had once, a fellow from Texas.
He was a veritable geyser of colorful metaphors, and I wish I could remember
more. These, at any rate, have stuck in my mind this past 20+ years:
[Of a woman who had set her sights on him] “She was comin’ after me like I
was a basket of corn and she was a hog.”
[Of a job of work we had been assigned, which he was confident we would get
finished quite swiftly if we buckled down to it] “Come on, Derb–We’ll be
through this faster ‘n a dose of salts through a widder-woman.”
And my all-time favorite Southern insult, from the movie Thunderbolt and
Lightfoot. “H’if they was to take yo’ brain
and shove it up a gnat’s a**, h’it would look like a B-B in a boxcar.”
