A Japanese word for person whom are prone to stay at home and watches anime/manga/video games. Although my friends and I like to mess around with that word saying like:
Goodbye my otaku brethern

Or
Fellow Otakus unite!
Or something like that

PS it is a negative word
Great I'm stuck with a non-otaku.

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?

In it's current, "Americanized" context: Social parasites. Usually fat, white Americans (with some exceptions) who, for whatever reason (unclear even to themselves), have chosen to become Japanese Nationalists based on their preconcieved notions of a non-existent Japanese utopia-- Notions which are developed from a lack of socialization and over-exposure to (mostly fantasy-oriented) Japanese animation (i.e., Anime, i.e., cartoons-- FROM JAPAN!)
Honesty is a bitch, huh?
Otaku: "DESU! POCKY! RAMEN! DURRRR!"

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.
