Sigh. Nerds are the technological autists. The geek, in a circus, was the guy who bit off the head of a chicken and other gross stuff. In Revenge of the nerds, Booger was the only geek.
And the gay guy was just the gay guy.
Of course, the meaning of geek has wandered until it is used as a synonym for nerd, as words often do, but only a nerd could tell you that.
