The expression refers to an Aboriginal ritual, in which a bone is pointed at a victim. In southern Africa, to throw the bones at is to use divining bones (a set of carved dice or bones used by traditional healers in divination) to foretell the future or discover the source of a difficulty by studying the pattern they form when thrown on the ground.
