any member of the cult following of either Stargate SG1 or Stargate Atlantis. these people can get very scary with their obsessiveness. usually pretty smart, but seem to have an infinite amount of useless knowledge.
Carson: What'd you do last weekend?
Janet: I totally skipped church for a Stargate marathon!

Pronounced (Jizz-Tee)
Severely screwing up the spelling of Gate to the point where you look like a total moron for screwing it up, thus having everyone joke about it for as long as you can remember. To put it in layman's terms; Gate, but mispelled

Sam: yeah. I'll be out by the front gste.
Sam: *gate
Andrew: lol, fucking moron.
