Someone who is obbsessed, and has no life outside of their obbsession. It's an insult in Japan. Mostly said like "anime otaku". Someone who is obbsessed with Japanese animation.
Not all otaku are bad.

Originally a Japanese term for "your house," "otaku" now refers to that bizarre suubculture that is obsessed with Japanese culture.

At least, that's what the otaku themselves would see it as. In reality they are a group of weirdoes so socially inept and obnoxious that other weirdoes cross the street to avoid them (on the rare occasions the otaku ventures outside). They really only like manga and anime, and seem to think that reading a comic or watching a TV cartoon originally intended for Japanese infant school students while wearing a too-tight shirt with random kanji characters emblzoned on it makes them a venerable Eastern sage.

The otaku believes that millennia of Japanese history, art and philosophy is irrelevant compared to a comic about bug-eyed schoolgirls battling robot space ninja goblins.
Otaku: "Worthless peasant gaijin! My weird enjoyment of comics that were written for children, despite the fact that I am a pasty grown man, means that my wisdom far outstrips yours! Can you smell sweat?"

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.

There's two different meanings to this word. The English one and the Japanese one. Who knows how otaku got translated to huge anime/manga fan. I do have a shirt that says Otaku...

English: Huge anime/manga fan. (Me)
Japanese: Insult. Someone who perfers staying inside all day. (Still me)
English: I am an otaku.

Japanese: ...I'm somewhat of an otaku. Yes, I need a life. Though I will do something with my life once I'm old enough to get my own house.

Japanese word/adjective which roughly translates into "infatuated", "extreme fanatic", or "obsessed to the point of being borderline deranged."

mainly used to describe the Wapanese people who watch ridiculous amounts ofanime. they, in turn, will use the word to dsecribe themselves, as if they are actually proud of being otaku. they don't know that the word has a negative meaning to it.
1: I'm so otaku, I have all the latest Yu-Gi-Oh things, and I just bought the new Ayumi CD! So ureshii!

2: Jesus Christ...
