Some words or phrases are nearly universal across a language, but some are used only by certain groups, or in certain areas. There are several that seem to be mostly used in Indiana -- "Hoosierisms".
A word that my grandfather apparently used was "juberous". It is most likely a corruption of "dubious" because that's how it was used. Having looked it up, it seems to have been used in the south and midland United States, so I guess this one is broader than actual Hoosierisms.
