Girls Are Good; Boys Are Bad

''So, you're telling me that it's wrong to say guys are better than girls in the slightest, but it totally fine to say that girls are morally superior to guys? Okay.''

When a girl is more well-behaved than a boy as if the girl is an angel and the boy is a demon. This mostly happens in Sibling Rivalries where the brother is the chaotic hell-raiser who's a pain in the neck for his parents, then there's the daughter who gets straight As in school, never gets in trouble in general, and has some artistic talent like being a musician or painter.

This isn't limited to just behavior. This includes performance in activities such as sports or music where the guy flounders and the girl succeeds at whatever it is they're doing. This is better seen in Boys v Girls where the suckiness of dudes is more well (and intentionally) put on display.
