About egghead

In U.S. English slang, egghead is an epithet used to refer to intellectuals or people considered out-of-touch with ordinary people and lacking in realism, common sense, sexual interests, etc. on account of their intellectual interests. A similar, though not necessarily pejorative, British term is boffin. The term egghead reached its peak currency during the 1950s, when vice-presidential candidate Richard Nixon used it against Democratic Presidential nominee Adlai Stevenson. It was used by Bill Clinton advisor Paul Begala in the 2008 presidential campaign to describe Senator Barack Obama's supporters when he said, "Obama can't win with just the eggheads and African-Americans."
