Egghead

In the American English slang, egghead is an anti-intellectual epithet used to refer to intellectuals or people considered too out-of-touch with ordinary people and too lacking in realism, common sense, virility, etc. on account of their intellectual interests. It was part of a widespread anti-elitist social movement that insisted that credentialed intellectuals were not the only smart people, but that serious human intelligence could be found widespread among ordinary people regardless of class, race or gender.
