Usually refers to someone scholarly and amazing. Being an Oakie means you have better living conditions than most other people. It also means you pay less for your education cause you're that amazing. They are probably the most sick-nasty people you will ever meet.
Oh man, I wish I was scholarly enough to be an Oakie... that'd be so sick nasty.
The second to lowest possible social level for a white person. Second only to trailer trash. People who collects hub caps and hang them on their house or fence, tape their windows instead of replacing them, and have a large collection of random shit scattered in their yards, in a seemingly organized chaos. They are generally a bit more shifty and withdrawn.
Run and git that hub cap, son. We'll give it to that family up the crick. They's good people, just oakies.
