Duppy is a word of Caribbean origin meaning ghost or spirit. Much of Caribbean folklore revolves around duppies. Duppies are generally regarded as malevolent spirits. They are said to mostly come out and haunt people at night, and people from around the islands claim to have seen them. The "Rolling Calf" (a scary creature said to have chains around its body), "Three footed horse", and "Old Higue" are examples of the more malicious spirits.
In many of the islands of the Lesser Antilles, duppies are known as jumbies. Barbados also uses the word duppy and it holds the same meaning as it does in Jamaica.
Originating in Central Africa, the duppy is part of Bantu folklore. A duppy can be either the manifestation (in human or animal form) of the soul of a dead person, or a malevolent supernatural being. But the word duppy more likely originating from the Ga language as most the African folklore and culture in Jamaica comes from the Ashanti people(a similar Kwa speaking people also from Ghana). In the Ga language of Ghana, Adope literally means dwarf but in Ghanaian folklore spirits are dwarves. In Obeah, a person is believed to possess two souls — a good soul and an earthly soul. In death, the good soul goes to heaven to be judged by God, while the earthly spirit remains for three days in the coffin with the body, where it may escape if proper precautions are not taken, and appear as a duppy.
The term "duppy" has been featured in various musical works from the Caribbean. According to Lee "Scratch" Perry, after Bob Marley wrote the song "My Cup", Marley was complaining to Lee that he was too "successful" and was being plagued by hangers-on and leeches, referring to them as duppies in the context of "human vampires" (or scroungers). Lee apparently consoled him by saying, "Look, we'll sort this out — we are duppy conquerors." Marley then wrote "Duppy Conqueror". The term "duppy" is also referenced in the song "Mr. Brown".
Several other Jamaican artists have recorded songs that refer to duppies, including Bunny Wailer's "Duppy Gun", and Ernie Smith's "Duppy Gun-Man". Yellowman released an album titled Duppy or Gunman. There was also a drum & bass single written by the duo Chase & Status called "Duppy Man" featuring Capleton's vocals from his track "Slew Dem". In 2008, Jamaican dancehall artist Demarco had a hit with the single "Duppy Know Who Fi Frighten" on the well-known "Shoot Out" riddim. Most recently, dancehall phenomenon Vybz Kartel released "Touch a Button Nuh" which mentions a duppy in the interlude. Collie Buddz sings about "duppies" in his song "Sensimillia". Roots Manuva refers to a duppy possessing him in "Witness (One Hope)", and released an album entitled Duppy Writer in 2010.
