I grew up in rural North Carolina, so I think I can add a few…
Hungry enough to “eat the ass-end out of a running skunk.”
When nearing the completion of a task we are “in the short rows now.” This is a reference to harvesting (priming) tobacco by hand when the shorter rows were saved until last.
Something unpleasant is like “getting hit in the face with a wet squirrel.”
When someone isn’t around and we don’t know why, then clearly they “went to shit and the hogs got him.”
Jammer
(About a homely woman) She’d make a steam train take a dirt road.
(Injury) He’s all stove up.
(Amazement) Oh, my staaawrs, ‘n’ little hoppy toads.
“We’ll be there, Lord willin’ and the creek don’t rise.” --Lady Bird Johnson
and my favorite,
“Boy, ah’m gon’ hit chew so haaawrd, you gon’ hum like a ten-penny finishin’ nail been hit by a greasy ball peen hammer !” --Brother Dave Gardner (I hope I got his last name right)
I’ll slap you nekkid. Variation: I’ll slap you nekkid into the middle of next week.
Scare a dog off a meat wagon.
Anyone who’s had a yard dog knows that yard dogs are prone (bad to even) run off with other yard dogs, be gone a few days and come back all beat up. This is known as a “dawg party.”
Southern little old ladies are referred to as dear ol’ thangs. “Bless her heart, she’s a dear ol’ thang.”
Dear ol’ thangs are prone (bad to) run around screaming: “Law!” “Law! Now where did I put muh handbag!”
If you are making a lot of something down south it’s a “mess.” A mess of greens. A mess of fried chicken.
Drunker than Cooter Brown. Ol’ Cooter was bad to drink.
“She looks like she was rode hard and put up wet.”
I’ve only ever heard it in reference to women, and at first, I was convinced that it was a lot dirtier than it is. It means so-and-so looks like a horse that was taken out, rode hard, and put away without being cleaned up.
