I think thats what their called anyway, its those south african trumpets, ever wondered what that constant buzzing was when you watch a match? Its those bloody trumpets that the fans keep blowing; even the players have commentated that it affects their playing as they cant communicate (If you ever saw S. Koreas goal against Argentina then that would be a result of this.) What do you think of them? Sure its south african culture but they shouldnt widely distribute them amongst fans, i think FIFA were even discussing banning them all together.
