Get a life! imp.
Hacker-standard way of suggesting that the person to whom it is directed has succumbed to terminal geekdom (see 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 1987 "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 years before achieving mainstream currency via the sitcom "Get A Life" in 1990.
