A Caucasian person with an unhealthy obsession with the Japanese culture. They worship an idealized thought of the nation, and typically aspire to move there. They take cannibalized form of Japanese speech, integrate it into English, and consider themselves more kvlt and Asian than anyone else. Common hallmarks of a wapanese: excessively pale, has a fetish for homosexual Japanese males, collects swords, claims to be a master at martial arts, eats Pocky, dines at Asian restaurants whenever possible, lives and breathes anime, does their own translations horribly, refuse to listen to anything but Japanese music, claim said music is better than any Western music, and lives on manga forums.
A lot of the people at anime conventions are wapanese.
