"Toxic masculinity" is comparing a man being upset with his girlfriend dancing with a stranger for 20 seconds to a woman feeling jealous about her fiancé paying to be surrounded by naked strippers
I mean I probably would feel some kind of way if I were the OP, but, perspective.
First off, we weren't trying to throw a party with strippers LOL. We were just going to go to a baseball game, eat some steaks, go out drinking, then come home the next day.
That's one of many ways to give examples of it.
Another is the idea that a guy should be upset/jealous with his girlfriend dancing with a stranger for 20 seconds at all to begin with.
That very notion is toxic masculinity, without needing to compare it to anything else.
Drunk girlfriend dancing with a stranger that's shown interest in a club is not something most men would be ok with. Even if you reverse the situation I highly doubt that's something women would be ok with either.
What's the buzzword to explain the reverse situation? I just figured "boundaries" was the explanation for both.
