I’ve called men nuts for considerably less than that, so has every woman I know
We have different experiences then 🤷♀️
I don’t think I’ve ever heard a man called nuts. Bastard, player, psycho, arsehole, oddball all used regularly for egregious behaviour.
But in my world “nuts” is reserved as a way of casually dismissing a woman for the most insignificant of misdemeanours.
