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.
me: hey, do you watch anime?
friend: anime sucks.
me: no, you suck. anime is good.
friend: your such a weaboo.
me: no, im an otaku.

Japanese word meaning obsessive fan of anything.Somewhat derogatory meaning that you put your interest above all else. Westerners tend to use it without the derogatory connotations. Rather, an otaku is someone who is a dedicated fan of anime and/or manga.

A negative Japanese word meaning 'nerd,' which anime-lovers have embraced and turned into a positive word defining a person who likes anime.

However, anime-lovers sometimes tend to cross the line, falling deeply into otaku characteristics themselves.
1. That kid's such an otaku; all he ever talks about is Dragon Ball Z and video games.
2. Dude, have you seen Naruto? Oh I love anime! I'm a total anime otaku! Kawaii!

A word that simply refers to people with an obsession for anime, video games or anything kinda like those things. Has developed a taboo because often times otakus are seen as the scum of japanese manga society. This taboo has been reinforced by otakus committing mass murders, rape and other crimes. In america to some people it is known as simply a fan, which for the most part it is, but also as an unhealthy obsesser. In japan their really isn't quite as much taboo since a huge portion of society reads manga, probably about 80 or 90% of males between age of 5 and 40 read manga on regularly. Even their Prime Minister, taro aso, who is an avid manga reader, refers to himself as an otaku, so really it isn't meant to hav any negative meaning.
Oh yeah hes an otaku
oh.... better make sure he doesn't get a gun
naw dont worry hes not one of those hes just a big fan
ohh... ok... but really make sure he doesn't get a gun

A Japanese slang term synonymous with "geek" that is used to describe people who have a hobby such as video gaming, anime, model kits, D&D and many others. Outside of Japan it is used almost exclusively for hobbies related to Japan, especially anime.

It is also important to note that many people make false assumptions and stereotypes against otaku. The most common fallacies are that they have no social lives and never get laid. While these are true in some cases, they are mere stereotypes and many otaku get laid on a regular basis. Such statements can be compared with saying that ALL black people are drug dealers. (It is also important to note that many otaku choose not to use the word in describing themselves due to the negative fallacies)

Another common misconception that has led to much asshatteryis that "otaku" has a set connotation, either positive or negative. This is untrue seeing as there are both practicing otaku who can be considered exempplary citizens as well as those who will never get laid. The words connotation is purely neutral. It describes people with certain hobbies and does not pertain to positive or negative behaviour.

Why these negative fallacies are often cast upon otaku and geeks, I do not know. There are people who can name useless facts about sports and music that rival the anime trivia of any otaku who are considered healthy. Furthermore, many otaku spend less time watching anime than most Americans spend watching TV. The idea that their social lives suffer from spending too much time on anime is a pure fallacy. All people have hobbies and interests that occupy their spare time, such as sports, telivision and music. Otaku are the same except their main hobby is anime. Most still have ample time left over for a healthy social life.

In Japan the word otaku is used to refer to someone who is extremely obsessed with something. Americans have adopted it to refer to anyone in their culture who is obessesed with the Japanese culture. Americans do not use it "incorrectly" as many people claim, they have just re-defined the word.
That Mallory girl is such an otaku... She watches anime, has been to more cosplay conventions then I can count, and can read, write, and speak Japanese!

1. (This is how it is used in Japan) Otaku means a person who sits alone and does nothing all day day and might watch anime, read manga, ect. In Japan, it is a term that is not taken as a complement.

2. (This is used in other places) An Otaku is a person who is obsessed in a fandom; usually Japanese. In other places (not Japan), it is not taken offensively.
1. Don't hang around with Haley, she is a major otaku.

2. That otaku can sing the hard to sing Japanese song and watches a lot of anime. (That sucked)
