Before you read the following, don't take me seriously. Ok you can. :D
Goatees and mustache
Honestly, I don't know what it's all about. I guess people like Jay and Silent Bob so much they not only dress like them, but the hair style is still popular. Just throw on some jeans, tie your hair in a ponytail, and wear your favorite black Radiohead t-shirt! The shoes are all up to you.
Females + Manga = Fetish
Young female nerds love manga! Of course they aren't the only ones who do. In fact everyone does! There have been many times when a young lady has asked me if I read, Vampires All Excorist. Yes, it's not a real manga but it sounds like one.
Niche Gamer
If you like Japanese roleplaying games, PC shooters, and/or PC strategy games you are a geek. Simple.
Cosplay
What the hell?! Now the anime cosplay isn't the worst, I say that because the women actually stress up in those skimpy outfits. It's actually the cosplay related to sc-fi/fantasy from either Europe or North America. Why? These people actually believe they're Jedi!
J-Pop and Rock
You know what? They can actually sing, I just can't understand what they're saying. There have been a few artists who have tried to break thru other markets. In North America, Asian pop singers aren't popular especially males. For one reason many Japanese singers bring a alternative form of music to what's already popular here. Most of times something heavy on electronic beats. Not to mention they'd have to change their entire image. Check out this article from a blog.
Internet dating
The love of internet dating. People have been forming relationships, and marriages over the internet. For geeks, the woman or guy you might love for a lifetime could be on Xbox Live or even in World of Warcraft right now so subscribe!
Opposite sex
Being scared of the opposite sex is a natural thing with nerds. Only time can fix it, and it is. How? The type of work we enjoy is becoming more noticeable and in fact we make good money annually. Money is attractive. We're getting a sense of S.T.Y.L.E. and have even created our own look. The weirdo you knew in high school blossomed into something amazing, and you can't resist them! I've ran into a lot of gorgeous women who love videogames; it's Grandma's Boy all over again!
