So, here's the opposite of my last post:
"Pejorative applied to anyone with an above-average IQ and few gifts at small talk and ordinary social rituals."
(note: "applied to" *by others*!)
"A person who has chosen concentration rather than conformity; one who pursues skill (especially technical skill) and imagination, not mainstream social acceptance"
"Originally, a geek was a carnival performer who bit the heads off chickens."
(I still say that nerd is a positive word and geek is a negative word)
