Top Definition
A female of superior wit and intelligence, she is the leader of other females in her vicinity. She recognizes that she is a bird, as are all females, but uses her lofty intelligence to manipulate and control all females below her.
Drew: I was talking to this girl, and she knows about how women are birds! It was amazing I finally found a female who isn't a bird.
John: Beware Drew, for she is the motherbird. She knows what she is and is more dangerous than the bird with the fanciest plume.
