(also “Code of the Geeks”). A set of codes commonly used in sig blocks to broadcast the interests, skills, and aspirations of the poster. Features a G at the left margin followed by numerous letter codes, often suffixed with plusses or minuses. Because many net users are involved in computer science, the most common prefix is ‘GCS’. To see a copy of the current code, browse http://www.geekcode.com/. Here is a sample geek code (that of Robert Hayden, the code's inventor) from that page:

The geek code originated in 1993; it was inspired (according to the inventor) by previous “bear”, “smurf” and “twink” style-and-sexual-preference codes from lesbian and gay newsgroups. It has in turn spawned imitators; there is now even a “Saturn geek code” for owners of the Saturn car. See also geek.
