DH's family uses "for crying under the sink!" -- Same connotation as "For crying out loud!"
My teeny, rural hometown has a word that I have heard nowhere else around the region, not even the other teeny towns nearby. I even tried to figure out its origin for a paper when I was in college, with no luck. (Although one older co-worker claimed her late husband had come up with it, I couldn't verify it, and she had no idea of the etymology.)
I'm outing myself here if there's anyone from my hometown, but the word is "Wallio."
It means -- in a sometimes oddly affectionate, sometime annoyed or exasperated way -- a city person who comes to the country to hunt beer.
