Reverse sexism is the practice of flipping sexist behaviours that typically apply to one gender so that they are instead applied to another (e.g., Barbieland's matriarchy in Greta Gerwig's "Barbie", Anne Hathaway playing an older woman in a romance with a much younger man in "The Idea of You", Sandra Oh's onscreen husband in "Killing Eve" playing a gender inverted "nagging wife" who no one will listen to and Eve treats with contempt)
