No, not the drink, I’m talking about another kind of spirit.
A jumbie is a general term for a spirit, but also the specific term for a restless spirit of the dead. Caucasian cultures usually portray ghosts as white, but the Caribbean jumbie manifests as a black shadowy figure. (The term duppy refers to the same thing.)
The aspects and ways of dealing with the jumbie vary in different Caribbean cultures. In some parts of Montserrat, there’s a jumbie dance (Not this one, but cool anyway. (Notice the people on the stilts in the background of that dance? Check this out.)), which goes on until someone is possessed by a jumbie.
To deal with a jumbie, leave a pair of shoes outside your house. It will spend the night trying to put them on (but they don’t have feet, so it won’t succeed — but still, one appreciates the fashion sense).
Jumbies/duppies can be vampiric, as well. Bob Marley’s song Duppy Conqueror is actually talking about his human leeches, though.
