I believe "geek-chic" to be an oxymoron. Being smug does not equal being socially maladjusted. Oh, I hear people claiming to be music geeks and sports geeks and I'm able to stomach it, but I heard someone claim to be a yoga geek the other day and it drove me out of a blogging slumber. Geeks are among other things authentic, and people should not trade on the geek name to lend some credibility to their affectations. I spent a semester of undergrad at a small engineering college, and I can say that true geek status is nothing to self-apply.
"Geekiness" can be defined as a sad inability on the part of some people to relate to other people, and a worrying apathy towards the prospects of doing so. Pastimes of the geek are secondary to social problems; however it follows from the very definition of the geek that those pastimes must be consistent with social isolation. Music, sports, and yoga are typically collaborative at least in practice and therefore off the itinerary of the proper geek. The geek social state is exacerbated by gender differences so inter-gender relationships are particularly difficult for true geeks. In turn, Internet porn, and Internet games where people never meet, but instead virtually kill each other while checking out attractive digital women are real geek pastimes. But God bless geeks. Where would we be with out them?
In a sort of unrelated note, I think there are many more male geeks than female geeks, but true female geeks have it worse.
