99% of tiktok/social media challenges/pranks. Just the other day I saw some kids climbing up a construction crane and filming themselves. I suppose that that is not really a prank but a few months ago, I heard about senior students in high school who thought it would be funny to criss-cross the hallway of toddlers with fishing line for them to trip over and film.
Call me a boomer (I'm not) but social media really brings out the worst in human group behavior.
