Mythical creature found marauding football fields around the world causing damage to unsuspecting players (particularly Korean Goalkeepers). Known to have particularly lethal kick. If directed at a football, can either break the net, goalkeepers hands or end up in a completely different postal zone. If directed at a player, has been known to cause lose of limbs and teeth. If seen, stand well back.
That Korean goalkeeper performed heroics until the Chui Zi appeared out of nowhere and broke the guys face with his knee.
