When being called Otaku basically means that आप are obsessed with something but it's और known for Anime/Manga/Videogame fans. Believe it या not being called Otaku in जापान is actually an insult (just in case any of आप were thinking of traveling to Japan, there's a little tip). I, for one, like being called Otaku (then again I live in the U.S.) because it reminds me of Konata Izumi from the ऐनीमे "Lucky Star" and we're a lot alike. :3
