Epidemic of girls who think they are too cool?

I've met a good amount of active sorority girls from ALL tiers of houses (top, middle, bottom, unranked) who think they are too cool for their sorority. Some are the influencer types and they seem to think they're above their sisters in their sorority. I wouldn't describe them all of them as mean girls per say some are actually nice but I guess they consume too much social media and post a lot on social media so that might affect their mindset. Anyone encounter this? I don't know if that's a bad thing or a good thing.
