William Gibson, one of the originators of the 'cyberpunk' science fiction genre, used the term "otaku" in his 1996 novel "Idoru". The meaning given, from a Japanese-translation computer function used by a character, was 'pathological techno-fetishist with social deficit'. The character so described spent much of his time online in a multi-user domain and subsisted on Ramen-type noodles and canned coffee. Although by Japan's rigorous social standards a "loser", the character was well-mannered and good-hearted.
"The otaku guys at my last school were into, like, plastic anime babes, military simulations, and trivia. Bigtime into trivia." -"Idoru", William Gibson

If you wear a shirt that says "Otaku" with the kanji script above it, and you are an american, you are an idiot.

Otaku is not something someone strives to be, nor is it a good thing. Americans, and I suppose other non-Japanese, do not understand the truth to this phrase.
I hate those posers who walk around in Otaku shirts.

Japanese: Someone who is an excessive fanatic on any subject or person, becoming experts on everything about. Otaku comes from the word to mean home, someone who's so obessesed that they never leave home.

English: An anime fan who has apparently never been to Japan. They have no idea what the word means but use it because of it's popularity in a retarded attempt to try to become Japanese. They feel anime is the only thing that makes Japan unique or special, and feel that anime as given them the "Japanese Aura of Enlightenment." They role-play as anime characters and dress up like anime characters because they are in such despair of their lives that they have to pass themselves off as anime characters. People with no self-esteem.
Japanese: That lolita otaku murdered a bunch of school girls, and apparently was stalking them well before he did it.

English: Hey Joe, there's that fucktard cartoon nerd, what did he call himself again? Oh yeah, an otaku. Let's kick his ass.

Otaku is what some hardcore anime fans call themselves.

Anyone who calls themself an "Otaku" is a complete prick and should be shot in the face over and over again.

A Japanese word, basically the equivalent of 'loser'.

Many Western anime/manga fans use it as a positive term for themselves, even though it is in fact negative.

However, there are people who know its correct use but are proud of being one anyway; just as some people are proud to call themselves 'losers'.

Calling yourself an otaku IS bad, as half of the definitions already state. It is the equivalent of a nerd or a shut-in, one of those people with skin the color of pasty white potato innards that obviously never leave their rooms. They speak badly-pronounced Japanese with broken phrases and improper words... like... say... OTAKU. American 'otaku' take pride in being nerdy pale-skinned freaks, and often scan over the latest hentai, yaoi, and yuri just to get off... most don't even know the ENGLISH LANGUAGE that well.

Most otaku sport a collection of Pokemon DVDs, trading cards, and pocky.

The word 'Otaku' is first of all an insulting and degrading Japanese term; Something that most of otaku don't seem to comprehend and take as a compliment,

They are also annoyingly obsessive anime fans that base their lives entirely on the anime that they watch and have this wild notion that Japan is some kind of Anime Wonderland with giant Robots, pocket monsters, and mystical wells that lead to the past and they go there thinking that Japanese people look and act like the anime characters that they see on celuloid. They also seem to think that speaking "otaku-ese" is equivalent to speaking fluent Japanese and think that Japanese people are going to be impressed with their lacking progress.

They also stalk Japanese natives in their own country and if you have a Japanese boy/girlfriend ladies and gentleman, hold on to them tight because these freaks are determined to snag a Japanese love at all costs and they're not known to leave natives alone until they get a yes from them after they've heard a hundred noes.
Otaku: Do you like Naruto?
Japanese Native: *walks away*

Otaku: Excuse me, do you speak English? Can translate this manga for me? *bubbly eyes*
Japanese Native: *walks away annoyed*

Otaku: Excuse me, hi I saw you from over there, I just want to say you're really cute and I love Japanese guys/girls. Do you have a boy/girlfriend?
Japanese Native: Umm...how about you choke on a fat lard and die?
