Jonah

A long-established expression among sailors uses the term, "Jonah", to mean a sailor or a passenger whose presence on board brings bad luck and endangers the ship. The meaning is based on the Biblical prophet Jonah. Later, this meaning was extended to mean, "a person who carries a jinx, one who will bring bad luck to any enterprise."

Every time Bob comes climbing with us someone gets hurt; the man is a Jonah.
