I'm from West Virginia and there are many examples of weird or strange phrases.
One is "don't beat around the bush" which means get to the point.
"So mad I could spit nails!"
My grandma says crick instead of creek.
Another my grandma says is "lessons" instead of homework. "Gotta do your lessons."
My dad says "fine as frog hair."
Another one is "I'm just standing here with my teeth in my mouth." That one is used as a response when someone reminds you to do something that you've forgotten. One time I forgot to get the garlic bread out of the oven and I was just standing in the kitchen.
Another one is "Shut that pneumonia hole," which is used when it's cold outside and you have the window open or the door down.
