I was always under the impression it was an Appalachian expression, but maybe that's only because my great-grandmother uses it (central WV), all of her kids use it, and the older members of my Dad's side of the family (SW VA) use it, too. I suppose they could have picked it up relatively recently, but they're mostly dyed-in-the-wool mountain folk. Most of their expressions are pretty... unique.

Of course, if it is Appalachian it could have originated practically anywhere and travelled almost anywhere west, north or south. :)
