Otakuese is the language most self-proclaimed "otaku" speak in. It is a mixed up jumble of (mostly) random Japanese words and the speaker's native language. In Otakuese, accurate useage of Japanese words is not important.
Ex: Baka - anything the speaker doesn't like.
Kawaii - anything the speaker does like.
Ex: 1: "Pokemon is sooooooo ka-WAII!"
2: "No it's not! Pokemon is totaly BAKA!!!!!"
Otakuese is largely unintelligable to members outside of the "otaku" community. However, it is noted that most "otaku" are able to understand each other fairly well. Although disagreements may break out about the particular useage of a word.
Ex2: 1: "She is so kakkoii!"
2: "No she's not! She's so bish!"
"Hello" in otakuese - "Wai wai neko-chan no baka wai baka neko nee!"
