The term 'Source of Bad Luck' can be summarized as a JINX, which is a superstition that brings bad luck to a person or situation. It is believed that a JINX can be caused by speaking certain words or phrases, performing certain actions, or even just being in the presence of certain people. A JINX can also be caused by an object, such as a cursed item or a piece of jewelry. In some cultures, a JINX can be removed by performing a ritual or offering a sacrifice.
