A person, who's of non-Japanese descent, who wishes that he or she was Japanese and claims to be an expert on all things Japanese. Usually, the person gets most of his knowledge from watching anime and reading manga and adamantly believes that everything that's made in Japan is better than anything else that's created in the rest of the world. They try to speak Japanese (which are usually slang words from Japanese anime) but fail at it so badly. They also believe that Japan is exactly as depicted in anime and thinks that Japan is some sort of fairy tale land. Pretty much, they are posers who wish that they were Japanese, worships the Japanese as if they were gods, and thinks that Japan is the center of, well, everything and they are extremely annoying, are very retarded and have a massive case of inferiority complex. They also claim that they are being oppressed by "outsiders" but the ironic thing is that they are doing the oppressing.
