&gt;Then what is it called when a woman does it to a man or a man does it to another man?

a man doing it to another man wouldn't be sexist so that doesn't make sense to have it's own sexist definition. as far as women doing it to men i think the only close example i can recall was the whole "dumb dad" era. i remember that being a popular trope in commercials (dad is too dumb to know how to use a paper towel). but i can't think of an equivalent phenomenon that happens IRL where a women talking down on a man is the same sexism that's coming from a man doing it to a woman. if a word exists, or should exist, it might have a slight different definition. mansplaining is just for the specific scenarios where men talk over women because they assume women are all dumb by default.

if men feel like there as an equivalent scenario where women will, very commonly, do some sexist conversation shenanigans with them then they are all by all means free to come up with a word for it. but mansplaining is something different.
