The widespread traditional belief your South Indian female is an 'Angry Black Woman', ie. that this woman is a physically dominant & verbally abusive virago who's prepetually emasculating & denigrating males. Essentially, the Oriental & Indian equivalent regarding the Sapphire Stereotype, with both images mutually strengthening each other.Historically, the perception that females hailing from areas of the erstwhile Madras Presidency are shrews is dependent on the traditional rehearse of matriarchy in Malabar. It goes back about into Ramayana, wherein the Dravidian girl is depicted as a 'Rakshasi' or giant black demoness & explicitly called an 'eater of males'.
