Get a life!

Get a life! imp.  Hacker-standard way of suggesting that the
   person to whom it is directed has succumbed to terminal geekdom
   (see {computer geek}).  Often heard on {Usenet}, esp. as a
   way of suggesting that the target is taking some obscure issue of
   {theology} too seriously.  This exhortation was popularized by
   William Shatner on a "Saturday Night Live" episode in a
   speech that ended "Get a *life*!", but some respondents
   believe it to have been in use before then.  It was certainly in
   wide use among hackers for at least five years before achieving
   mainstream currency in early 1992.
