A non-Asian person who has an identity crisis and thinks he/she is Asian. Or a non-Asian person who really wishes he/she is an asian. Typically watches anime and hong kong movies, listens to K,J,C-Pop, and tries to get Asian friends. Usually tries to learn an Asian language as well.
Look there is another asiaphile wearing his Dragonball Z t-shirt that he never washes. That guy is trying to score with those ugly, fobby Japanese chicks by asking them to teach him Japanese in exchange for him teaching them English.
