geek
1 : a carnival performer often billed as a wild man whose act usually includes biting the head off a live chicken or snake
2 : a person often of an intellectual bent who is disapproved of

I prefer this definition: “Geeks are fast becoming to contemporary popular culture what beatniks were for the 50s and hippies for the 60s. Their motif is technologically based, but their experience is rooted in social alienation, isolation and dedication. Geeks tinker with their PCs in the way greasers once suped up their hotrods… geeks remind us that today’s younger generation need not be nostalgic for the glory days of the 60s – they have found their Woodstock online.”
