I disagree that the usage is “you are behaving like a woman”, I would say it’s more “you are not behaving according to your gender”. Men are called it for not being masculine enough, for being perceived as cowardly or weak, while women are called it for not being feminine enough, for speaking up for themselves or rejecting male attention.
