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.

this word was originally used in japan to describe someone who enjoys anime and manga. the term later became derogatory when a japanese news station used it to describe a serial killer who had been a hermit and was obsessed with anime, manga, and doujn. When it crossed the pacific to America, otaku became a word popularly used to describe anime-con goers. the Japanese, who are always quick to pick up on American fads, soon used the phrase to describe a cool "geek chic" type of person, often found in the Akihabara district of Tokyo.

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.

Otaku are smelly, furry, plump creatures that are usually found in their natural habitats: their own mother's basements or in their dark rooms where the only sources of light are the bright glow of their computers or television
my friend is an otaku, he stays in his room on the computer and TV all day

A person who loves to watch anime and read manga and also admires the Japanese culture, but not to the point of denouncing their own, that would make them a weeaboo. Being an otaku is basically being apart of a whole new culture, an it's great! Just don't become a weeb.
"Hey, do you watch anime?" "Yeah!, I am an otaku, you?" "So am I!"

1: Another version of the word "you" in Japanese (which includes anata, omae, kimi, and so on) this word when used by someone, connotes that that person would like to stress the boundaries between your relationship. You are only to be acquaintances and not friends.
2: A new slang term, rooting from the first definition, referring to fanatical or obsessed people, usually known to be withdrawn in many cases.
