What's the most absurd thing you've seen someone refuse to do because of toxic masculinity?

Back in my country, bottled mineral water used to have a pink cap when it was non-carbonated, and blue cap for the carbonated one. I guess, I don't even have to finish the story, at this point everyone can imagine... But yeah, in primary school I had class mates who refused to drink the non-carbonated one, saying it's "gay water".
