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)
