One who excells far ahead in school but is rather stupid in the sense that they are close minded and not tolerant of people different than themselves. They often see themselves as better than many other people and judge people solely on their academic achievements and not on their personality or moral values.

The opposite of this is a dumb genius. One who does not do well in school but is very street smart and if he put in effort would do well in school as well.
Guy 1: hey I got an 85 on that paper man it's not too bad what about you?

Guy 1: at least I'm not a smart idiot
