neep-neep
     
        /neep neep/ [onomatopoeic, from New York SF fandom] One who is
        fascinated by computers.  Less specific than {hacker}, as it
        need not imply more skill than is required to {boot} {game}s
        on a {personal computer}.  The derived noun "neeping" applies
        specifically to the long conversations about computers that
        tend to develop in the corners at most SF-convention parties
        (the term "neepery" is also in wide use).  Fandom has a
        related proverb to the effect that "Hacking is a
        conversational black hole!".
