These are people in american culture who watch anime all the time. They buy ever peice of anime style cloathing that they can get their freaky hands on. They stay at home, surfing the net, only socialising with people over message boards, and very rarely at cons, or conventions. They have no 'life' or a love life. They enjoy staying up late to watch that gundam episode for the 45th time.
People who go to the anime club at my school, they scare me.

Many emo kids, goths, ravers, furry and anime fans, gays, and pretty much anyone else who is different are targeted fairly often for mockery by Something Awful and Portal Of Evil crowd.

Wouldn't it be funny if the emo kids, goths, ravers, furry and anime fans, gays and anyone else these guys targeted all joined forces and mocked them back?

Nah. That wouldn't be nice. It would be funny, though.
I'm not really into anime, so I guess I don't qualify as an otaku. It's okay to like anime, though. Life wouldn't be as interesting if everyone were the same.

Get the otaku mug.
A person, mainly a fat American girl, that loves anime/manga and a few Visual Kei bands such as Dir En Grey and An Cafe(possibly the only bands they know). Someone who thinks that just because they watch anime, eat very few Japanese food(pocky snacks also) and know the word "kawaii", they are also Japanese, despite how terrible they look. Someone who can't use chopsticks for shit but uses it anyway. Someone who eats cereal with a Chinese spoon and save Ramune bottles. A very ignorant person indeed.
Otaku: "THAT'S SUCH A KAWAII HELLO KITTY PURSE! Can I glomp you?!"
Me: "Stfu,gtfo."
Me:"Here's a true fact: The Japanese HATE you...."
