I agree with you on ‘man up’. That said, I know it’s a joke and I’m totally fine with jokes of any kind in the right context. What I’m talking about primarily is when someone is in a poor overall financial situation. Then uses the phrase as a justification for making their situation worse with terrible spending. Joking about a thing vs normalizing a detrimental behavior is kinda what I mean. Idk I don’t think people shouldn’t say it in general it’s just something thats been on my mind recently. Mostly because one particularly annoying person in my life uses it a lot.
