confessions of a hillbilly

This past weekend I had the privilege of helping plan a large party for college students in West Virginia. It was a lot of work, but the benefits were many, and the joys plentiful. One such benefit was being in charge of a game called Hillbilly Hangman, which, to the dismay of certain moonshiner traditionalists, didn't actually involve hanging anyone. We simply used the childhood game to express and explore a variety of mountain man traditions. Here were some of my favorite words:

little brown jug
tractor pull
Everthung's A Doler Store
"skinny little feller"
cars on blocks
Moonshine Market
"you've been pitsnoggled!!"

My favorite word though, and the one I used most often (when new people came up), was the following word:

M _ D _ O _ _ I N ' (this is after the letters they would usually guess)

Now a certain young man from the hills of Virginia took one look at that phrase and declared the answer with such volicious certainty that I was taken aback. I couldn't believe he got it so quickly, mainly because no one else had. At one point, a group of over-educated students from a top-rated university were in such a feverish debate over the possibilities of this word, that they resorted to mathematical equations and Old English grammar books. The debate kept going on and on, and they couldn't decide what to pick. One would suggest something and another would say, "No, that's not possible. According to the laws of . . . ." It was hilarious, especially when their poor cowboy got hung, and they still were missing three letters.

So, let's see if you're smarter than they are. Any ideas?
Think hillbilly and it shouldn't be too hard.
