: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.
