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.

A Manga, Anime, and video game (particularly RPG) fan who is obsessed with anything Japanese and Japan in general because of anime and manga. The literal term in Japanese is derived from home, so basically it means a person who stays at home all the time. They shut themselves away from the world as their ability to socialize to normal people slowly deteriorate and even if they are not Japanese they want to be Japanese so badly. they learn Japanese so that they can watch raw anime episodes and read raw manga. This is the main golden achievement an Otaku can do especially when other Otakus are jealous of this amazingness. They wear clothing with Kanji and their favorite anime characters. They collect anime figurines, fill their walls with posters of their fav anime/manga, life size anime characters, manga library collections, and DVD boxsets (there is much more trust me). They probably have played every single Final Fantasy Game out there. Their favorite food to eat it Ramen, Ramune soda, pocky, sushi, and other various foods that come right out of an anime. They include words like "baka" and "nee~" or "Kawaii" in their everyday lives, yes, even if they do not speak Japanese. Basically just picture a creepy dude with glasses reflecting the glare of light from his HD TV in a dark room, eating ramen and everything anime filling the room. But not all otakus are like this! there are different levels of otakuness.

Otaku is a term used for anime fans. However lately it is a word used only for "eleet" followers of the genre. Most of us have liked " Japanese anime" in one way or another but it is the Otaku that knows what happens in each and every episode of every anime series ever to have existed. The problem is Otakus have broken off into their own snobbish inner circles. They get angry when someone gets a small fact wrong about a certain show and they insist on adressing each other with words such as "chan". They also get very angry and impassioned in meaningless debates such as who would win in a fight between Darth Vader and Sephiroth. Naturally they will always vote for the most girly metrosexaul inspired male character with a huge sword in any discussion pitting famous characters against each other. In the end Otakus are not unbarable because they dress in cosplay or draw fan art. They are unbarable because they are over obcessed, shun originality, and spaz over trivial bull crap. It could be argued the new gen otaku are far more extreme then their first generation counterparts. Older appreciators of anime on average are more laid back despite their eccentric habits.
I enjoy anime casually but it is the otaku that sleeps with a life sized sailor moon doll and quotes Naruto word for word!

One who obsesses about something or someone to an unhealthy extent, sacraficing most, if not all, of their social life.

Often used (incorrectly) by American anime fans as a trendy term to describe themselves.
Correct usage: anata wa otaku desu. (You are a nerd.)

Incorrect usage: I like anime, so I'm an otaku. (This is, however, correct if the person saying it has no life outside of anime.)
