Okay, imagine you and your friends are playing a game where you all pretend to be superheroes. You might make up stories about how your characters have special powers and you might act out fights and adventures. You all know that you're just pretending and it's all made up, but you want to have fun and keep the game going.
Well, in professional wrestling, they do something similar called kayfabe. This means they act like the stories and fights they show on TV are real, even though everyone (including the fans) knows that they're not. It's like they're all playing pretend together, but trying to make it seem like it's real.
So when a wrestler gets interviewed, they might talk about how much they hate their opponent and how they're going to do anything to win. They might even act angry or upset to make it seem more dramatic. But really, they're just playing a character and they might be friends with the person they're supposed to be fighting against in real life.
Kayfabe is like a way to keep wrestling exciting and interesting for fans. It's like watching a movie or reading a book, where you get invested in the characters and their stories even though you know it's not real. By pretending like it is real, wrestling can be really fun to watch and enjoy.
