Top Definition
A geek who picks on other geeks to gain favor with jocks in a desperate attempt to escape geekdom and become popular.

Judas geeks rarely feel comfortable around other geeks, never fully accepting their inner desire to partake in geek activities, nor around jocks, whose language and practice they fail to understand and whose physicality they fail to match. The end result is a scrawny, pastry individual in ill-fitted pseudo-fashionable clothes who will backstab anybody to gain a little bit of popularity.
- It's funny, isn't it? As soon as Lisa appears, Ben refuses to talk about magic or RPGs.
- I know, he's such a Judas Geek.
