I wrote an article discussing how to define geek: www.geekwishlists.com/geekdefinition
When I was growing up I used to geek out over Star Wars.
Describing a person that has an high amount of intelligence with an exception with being annoying or weird.
"I don't like Jeremy, he's a geek"
"He's the teacher's favorite student, since he's a geek"
A verb for getting high. Most notably used by hip-hop/ rap legend, Smokepurpp, in his modern day classic "I Geek Alot".
Damn, i geek alot, I'm always off xanax and lean....
