A Japanese term that refers to the Japanese equivalent of a nerd or a geek but with an extremely negative connotation. Usually, otakus stay at home, don't go to school nor work, and don't try to do anything to better themselves or their societies and spend all of their time surfing the internet, play video games, or watch anime. The more extreme ones also sleep with pillow cases with anime characters on them and have entire rooms that are filled with nothing but anime goods which includes rooms full of anime figurines, which are sometimes found naked. Pretty much they are embarrassments towards Japanese society and the Japanese, themselves, believe this.

In America, however, anime fans mistakenly refer to themselves as otakus and has taken on a more positive connotation. But, otakus, in this sense, are hardcore anime fans. But it is still agreed upon that otakus in America are just as annoying as their Japanese counterparts since the ones in America believe that they know everything about anime, manga and sometimes fiction in general and they claim that they are never wrong in regards to their knowledge regarding anime and manga. Just like their Japanese counterparts, they love collecting figurines and have rooms full of nothing but things that are related to anime. The more extreme ones of these, however, are sometimes called weeaboos and actually wish that they were Japanese and worship the Japanese as if they were gods.
Otakus are infuriatingly annoying in both Japan and in America and it's generally not advised for someone to call himself an otaku, especially in front of a Japanese person since they look upon them with extreme disdain.

an otaku is a word commonly used to describe someone who is either obsessed with Japanese culture or a geek who spends all his/her time watching anime and never leaves the house. these are both false; that is the definition of a weaboo. an otaku is simply a fan of anime and manga and stuff like that. not a geek who has no life; not a weaboo. but sometimes, otakus try too hard and do turn into weaboos. for a better idea of the difference between otakus and weaboos, read my definition on weaboo.

A term that is miss-used by both the Japanese and other countries.

In Japanese its the honorific of home. meaning the person is a shut-in. They also refer to a community that visit certain places such as akihabara, Tokyo train station, ect. Otaku in America and other places is a term to describe fanatic fans of a certain thing ,mostly anime. In japan there are also other types of otaku such as train otaku "IE train station", Bridge otaku, anime otaku, music otaku, ect...

In America people think that it is being used wrong, but in actuality its just being used in the alternative term.

In japan the term is sometimes refereed to as something really bad. But their is a growing population that take the name otaku with pride. Demonstrations are being held. ect ect...
EX. how can a train otaku be an "otaku" if he actually leaves his/her house to go look at trains.

EX. how can an anime otaku be and "otaku" if he/she goes out to cosplay shops, akihabara, and other social events such as cons, "maid cafes", where the person HAS to meet other people.

there are several definitions of "otaku"

1) polite(correct) way of saying house
2) many people mistake the actual definiton of otaku when it comes to things such as "anime otaku" or "game otaku"
it used to be a insult but recently, the definition has changed to a more positive meaning, although the word can still be used as a insult, it is more commonly used as a compliment
Ex. anata wa computer otaku desu ne (your a computer otaku)

although it is unclear as to when the definition switched, many believe that it may have happened with popularity of animes and mangas going up

manga otaku
electronic otaku
anime otaku

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."
