Ootaku?
Otaku is derived from a Japanese term for another's house or family (お宅, otaku) which is also used as an honorific second-person pronoun. The modern slang form, which is distinguished from the older usage by being written only in hiragana (おたく) or katakana (オタク or, less frequently, ヲタク), or rarely in rōmaji, appeared in the 1980s (http://en.wikipedia.org/wiki/Otaku)

Boku wa Otaku desu ka?
Well I don't really know.. But to compare myself with my friend, while they likes Korean Artist more than anime, and me the vice-versa.. I think I'm a lil' bit of Otaku.. Just a lil bit, ok? Not too much.. I love anime, but not to collecting the model or anything like that. Just like to watch.. And besides, I love Japanese language, and how they can make it sounds so cute... lol..

I know people usually thinks that Otaku is strange, nerd, fat, and.. well.. so many bad other impression. I don't think it's valid in my country. Usually Otaku here maybe a lil freak (me? No! lol), but the impession is still good.. :D There still no Japanese-like Otaku here.. :D
