JustOneMinute: Nerd Patrol
She has gone to high schools and colleges, mainly in California, and asked students from different crowds to think about the idea of nerdiness and who among their peers should be considered a nerd; students have also “reported” themselves. Nerdiness, she has concluded, is largely a matter of racially tinged behavior. People who are considered nerds tend to act in ways that are, as she puts it, “hyperwhite.”

Since they use “nerd” and “geek” interchangeably I assume that “geek” = “hyperwhite” too.

I am sure this was meant as a vague insult, but if so, I think the actual result is that it implies that nerd behavior (which is usually identified as studious, technically savvy, intellectually engaged and socially inept) is not common in non-whites. I think if I were non-white, I might be insulted by that.
