Definition of otaku:[spoiler]A term literally translating to "you" from Japanese to English. Although more recently, since around the early 1980's, otaku has shifted more into a slang word and is commonly used in Japan as an equivalent to "nerd" or "geek". Also, it can be used in a less disrespectful way to mean one with an obsession or great interest (typically in manga/anime fandoms). Another way of using it could be to describe a shut-in or socially awkward person. In the west, however, otaku is a derogatory term used to describe someone who should be looked down upon for their interest in anime or manga. While technically an insult, most otaku will accept the adjective and frequently identify by it.[/spoiler] Definition of weeaboo:[spoiler]One who purposefully appears to be stereotypically Japanese.
