"Duppy is a Jamaican Patois word of Northwest African origin meaning ghost or spirit. Much of Caribbean folklore revolves around duppies. Duppies are generally regarded as malevolent spirits. They are said to come out and haunt people at night mostly, and people from the islands claim Johanna to have seen them. The 'Rolling Calf', 'Three footed horse' or 'Old Higue' are examples of the more malicious spirits.
In many of the islands of the Lesser Antilles, duppies are known as jumbies."
