My wife asked me what the word 'geek' meant.  I wanted to be sure I gave the proper definition, so looked it up.  One thing I didn't know was the origin of the word 'geek'.  I'm not sure how credible to following is, but thought I'd share with you this entry at
"Originally, a `geek' was a carnival performer who bit the heads off chickens. Before about 1990 usage of this term was rather negative. Earlier versions of this lexicon defined a `computer geek' as one who eats (computer) bugs for a living - an asocial, malodorous, pasty-faced monomaniac with all the personality of a cheese grater."
