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.)

Japanese: Someone who is an excessive fanatic on any subject or person, becoming experts on everything about. Otaku comes from the word to mean home, someone who's so obessesed that they never leave home.

English: An anime fan who has apparently never been to Japan. They have no idea what the word means but use it because of it's popularity in a retarded attempt to try to become Japanese. They feel anime is the only thing that makes Japan unique or special, and feel that anime as given them the "Japanese Aura of Enlightenment." They role-play as anime characters and dress up like anime characters because they are in such despair of their lives that they have to pass themselves off as anime characters. People with no self-esteem.
Japanese: That lolita otaku murdered a bunch of school girls, and apparently was stalking them well before he did it.

English: Hey Joe, there's that fucktard cartoon nerd, what did he call himself again? Oh yeah, an otaku. Let's kick his ass.
