The term "otaku" seems to have been introduced to anime fans in the US and other countries via Studio Gainax's "Otaku no Video 1985," a self-parody film.
Otaku, meaning probably "venerable house," refers to someone who has a devotion to a subject or hobby (not necessarily anime) to the point of not leaving home. For instance, an otaku fan of a particular movie star could quite possibly know all of the films s/he has been in, their birth date, time of birth, shoe size, favorite toothpaste, etc. Generally speaking, calling someone an otaku in Japan is an insult, implying that their social skills have atrophied or never even developed, due to their manic involvement in their chosen fandom.

In America, the term is used to denote a zealous fan, usually of anime and/or manga. Due to its introduction to most people's vocabulary through its tongue-in-cheek use in Gainax's film, "otaku" tends to have a much less dire definition overseas.

When dealing with Japanese people, however, it may be best to keep in mind the modern Japanese image of an otaku -- Someone who only leaves their home to eat or shop, if at all, with an overwhelming and unhealthy obsession about something. It can as easily refer to a stalker or sociopath as it can to a harmless anime buff.

Best to avoid the word altogether if one is not sure of the context in which it will be received.
Positive: "Oh, wow! Check it out: Neck-through, Floyd Rose locking tremolo and an optional push/pull coil tap!" (slaps forehead and laughs) "Man, I am such a guitar otaku, aren't I?"

Negative: "Stay clear of Toshi, man. He's such a RQ otaku, always online. Bet he's never actually even talked to a real-live girl before... You never know when he's gonna' snap, right?"

Basically Japanese for "nerd".

It has been adopted as a description by many anime fans who are either too retarded to realize it's an insult or are so obsessed with Japanese culture that being called a Japanese word is great no matter the meaning. These sub-categories of anime fandom need to get a proper education and get a life, respectively.
I'm so otaku >.< :D :D :D

Shut the fuck up you retarded piece of shit. Otaku is a fucking insult, okay? Learn to read and maybe you'll figure out these "complicated" definitions. Fucking illiterate bastard.

Used by shitheads who watch anime and "love" Japanese culture, and think of themselves as a cool, relevant people who watch anime, despite the word meaning some loser who stays inside all the time and has absolute zero social skills and life in Japanese.

Keep calling yourself that and you will live up to the name.
Fucktard: Omigod, I love anime, that makes me an Otaku, right?
Me: Nah, it means you are a complete fucking loser. Call yourself that again please.

An Otaku is someone who watches large amounts of anime. Otakus are often diagnoses with sever down syndrome and other mental cancer. Otakus will try to push anime on you more often than not and brag about how much of a weeaboo they are. Currently, Otaku also try to blend into Asian culture. Otaku try to speak Japanese in shitty, high-pitched voices, and attempt to know so much about the country. The song "I Want to Go to Tokyo" is a prime example. There are other compilations on the internet that one can use to find out more about the autistic breed of Otaku.
"Jeremy is such an Otaku."
"Otakus should paint there walls with their brain matter."
"I'm such an Otaku, I watch more than fourty anime shows!"
"Otakus, please kill yourselves."

Means "Nerd" in Japanese.
People who don't know it call themselves otakus because they love anime and they're addicted to it.
Like weeaboos,for an example,they love anime too much.

This isn't anything good if you're trying to use it when you know its meaning.

What it means is an Japanese Nerd.
He has been calling himself an "otaku" for a half year now. He still didn't realize at all it means a Nerd,in the Japanese genres.
