Tell a man his female partner is "too good/too much for him".

Reaction: "I know, dude! She's so fucking hot!"

Then tell a woman her male partner is "too good/too much for her".

Reaction: "Are you fucking kidding me? Are you saying I'm not good enough for this? Who the fuck do you think you are?"

Many women love being told they're better than everyone else on virtually all aspects. That's why you have this long-lasting trope in film and TV of "Constantly reminding the male character that he's a doofus who doesn't deserve the girl while she, for some unexplained reason, is the most amazing entity in the world".
