Origin of dragon lady
A domineering or belligerent woman, as in They called her the neighborhood dragon lady—she was always yelling at the children. This slangy term was originally the name of a villainous Asian woman in Milton Caniff's popular cartoon strip Terry and the Pirates (1934–1973), which ran in many newspapers. It was transferred to more general use in the mid-1900s.
