From Hector Garcia's A Geek in Japan:
"At first glance, it seems like a kid with a supercool sweater with a Japanese character. The problem is that the character ? means �hemorrhoid� in Japanese. Probably the designer confused the character ?, which means �samurai� and is pronounced �ji�, with the character ? that means �hemorrhoid� and is also pronounced �ji�� Both characters are graphically very similar but the meaning is totally different!"
