Now it's the dog water challenge, using her sound. And that right there, is the other big thing. People that would never do it, now just have to karaoke it. And now you have a feed full of people doing the dog water challege to the same repeating sound.

Rinse, repeat with another shmo.

And that's just one. They have so many other little brain worm dopamine hits to keep you there and scrolling. And they keep adding more.
