loona effect

The conditioned aversion towards a thing due to the annoying followers.

Comes from the kpop girl group Loona, whose fanbase made it their mission to spread the word "Stan Loona" on each and every unrelated topic, ironic or not, thus annoying a lot of people who in response refused to even acknowledge the group itself.

1: man, everyone keeps talking about Game of Thrones. It's started to annoy me so much, I'll never want to watch it.
2: same fam, got the worst Loona effect.

The Zach Effect

The Zach Effect, also simply called Zach Effect is referring to when a guy gets a haircut, and because of that, looks younger. This often only applies to guys who had noticeably longer hair before their haircut. This is sometimes because the guy had short hair when they were younger, and has just got it back, but the effect can happen otherwise as well.

"Did you see Max's new haircut?"
"Yeah, dude. That's the Zach effect at work."
