japfapper 

An uncommon and exciting term for those who practically "get off" to Japanese (or Asian in general because they're idiots) things such as but not limited to anime, manga, j-pop, Asian boy bands, etc. Typically the female species will develop bad habits of wearing strange clothing simply because they saw it on an Asian model or it came from an Asian country, the males may also do this but usually they seem to be a little more careful about revealing their sick obsessions.
Most commonly seen with such people is their desperate need to attempt to be Asian, despite not actually being of Asian descent.
