What is a geek? Merriam-Webster's Dictionary offers the original definition of "a
carnival performer often billed as a wild man whose act usually includes
biting the head off a live chicken or snake," as well the more modern, slangier
meaning, "a person often of an intellectual bent who is disapproved of." (No
dictionary that I've yet consulted - not even the relatively "hep" American Heritage
College Dictionary - mentions the current computer-affiliated sense of "geek".)
