Popobawa is a Swahili name which translates literally as "bat-wing" (from Swahili popo, "bat", and bawa, "wing"). This name is said to have originated as a description of the dark shadow cast by the spirit when it attacks at night: it does not refer to the actual form of the spirit, which is liable to change. Swahili speakers also use a plural form of the name - mapopobawa - to refer to multiple manifestations of the feared spirit.
