A negative phenomenon where foreigners who go to Asia try to look like ancient Japanese Samurai by growing their hair to long lengths, and tying it in a bun at the back (possibly with a lock or two of hair loose for shock affect). They do this because they are confused about their own identity and are actually shallow enough to think that you can become something in complete essence by merely duplicating what it looks like. It is also generally accompanied by growing aesthetically repulsive amounts of stubble with a smile/sneer and *I'm cool attitude*.
Man I can't believe that clown! He comes walking into here looking like a Samurai Wannabee and actually managed to pick up that chick! That guy is such a fake!
