IMO, it's just being overly confident and stubborn in your explanation of something. specifically in relation to the two sexes (or genders, depending on the scenario)
Anything else just doesn't apply. But i also have a pretty strict definition of anything like this tbh.
That's rather broad i think. Like are we including people who don't socially communicate very well? Like autistic people for example. I like to define things specifically enough that they have an explicit category. I don't interact with people physically very often, i'm not good on picking up cues, and often just completely ignore their physical state, because i'm in the middle of doing something else.
Forgive me if i'm rather brazen here, but like, just fucking tell me i'm being a dumbass and explaining something i don't need to. It's fine.
