Poor looking, unkept, dirty person. So dirty they look as if they have been performing manual labor digging dirt.

"Origin of the word is from southeast Missouri."
You better get cleaned up, because, I don't want to be seen with you looking like a tiff digger!

I got to buy some new clothes, so I don't look like a tiff digger!

Those boys down the street looked like a couple of tiff diggers.
