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

Otaku is a Japanese word used for foreigners who are obsessed with Japanese culture. A lot of confusion has been made over the years, and people are starting to think Otaku is someone who stays home all day and does nothing but watch anime and jerk off to pictures. This is called a Hikikomori. The difference is that Otaku get out, and have a life, and pass in school, regardless by how much, and talk to other people, depsite the topic. Hikikomori are shut ins, and do leave the house for anything and don't socialize. For any reason. Whatsoever.
*Knock Knock*
Delivery Man : You there?
Hikikomori : *Fap fap fap fap*
Delivery Man: I have a package for a Mr. Smith
Hikikomori : *Opens door naked* Thanks! *closed door and faps*

Otaku 1: Hey, did you hear? They're coming out with a new season for Naruto!
Otaku 2:Naruto is gay, you have to watch anime that deals with Japanese life, like Clannad. You're a fake.
Fake-Otaku 1: No way, Bleach is better than anything.
Otaku 2: Whatever.
Japanese Guy 1: God-damn-it. I hate those Otaku's
Otaku 2: OMFG A REAL LIFE JAPANESE GUY!!! HIIIII!!!!
Japanese Guy 1: Fuck.

Many people assume that one who enjoys Japanese anime and manga is automatically labeled as an 'Otaku'. This is completely untrue. Cosplay and the love of anime and manga does not make you an otaku.

An otaku is simply one who over-obsesses a certain hobby, in most cases anime and manga. Typically, this is a negative thing to be called in Japan, although North Americans have begun to take a liking to the word.
American person one: Steve knows everything about Love Hina. He's such an otaku.
American person two: Yeah, he'd be so glad to hear that.
---
Japanese person one: That Tsutomu Miyazaki sure was an otaku.
Japanese person two: Yeah, what a psycho.
