slang for a ghost or spirit, but nowadays is used as
slang to hit someone or beat someone up, or take them for a complete derkhead. duppy is degenerately used by black
people who are looking for a fight or little white kids who want to or think that they are the black gangsters....eg
"

sam"
"i will take you for a complete derkhead fool"
Watch me duppy this waste
