Why do all my friends send me the same meme format?

That's just how internet culture works these days. Memes spread like wildfire through friend groups and social media because everyone wants to be in on the same joke. When one format takes off, especially something absurd like skibidi stuff, it becomes this shared language where people bond over the ridiculousness of it. Your friends aren't necessarily trying to be original - they're just participating in something that feels current and communal. It's kind of like how back in the day everyone would quote the same movie or song lyrics. The format itself doesn't even have to be objectively hilarious; it's more about the fact that *everyone* is doing it that makes people keep sending them around.

The other thing is memes have a pretty short shelf life. Something can dominate for a week or two and then completely die off, only to get resurrected ironically months later. Right now you're probably in that peak saturation phase where it feels like every notification is another variation. Don't worry, in a few days everyone will move on to the next thing and you'll be wondering what all the fuss was about. Just ride it out or mute the notifications if it's bugging you that much. After running competitively for years, I've learned the hard way that sometimes you just gotta let trends pass by without overthinking them - similar principle applies here.
