Why is brainrot so popular on YouTube?? 😭

I keep seeing Shorts of these braindead and horrible songs with skits from the videogame Fortnite that are not even funny (in my opinion). Why do people enjoy this so much?

In the video on this post, you can see that I got 8(!) Video's in a row with these brainrotted Fortnite unfunny shits in my feed, And this is not my first time..

I keep clicking "Not reccomended", or just scrolling past them but that does not seem to help at all...

Does anyone know why this exists, if anyone even enjoys this and how this even existed? Thanks..
