This is a combination of nitwit and idiot, with both words indicating that someone is not to smart. I like the way the word sounds. If you put this as an equation it would be, feeble-minded+stupid=nitwidiot.

Commonly heard on high school and slightly less frequently college campuses;a not so clever fusion of nitwit; i.e.one of low intelligence, and idiot; one who is mentally underdeveloped; sometimes seen spelled {nitwitiot};
The professor has difficulty separating the real brains in this class from the mere %s nitwidiots and suckups.
