A gossiper, gossipmonger... From Urhobo language, "Avwebo"/"Aʋɛbo", meaning the favourite amongst multiple wives in a polygamy; mother of house or senior wife. De facto in charge of the compound, having the ears of the husband and privy to all his affairs, Aʋɛbo would often serve as the goody-two-shoes conduit for gossip in order to win favour with her audience.
