It started out small. Maybe a kid would start something in the hall while his friends pulled out their phones, recorded it and posted it to TikTok. Then they realized if they start a larger fight on the way to lunch they'd get more views because kids had their phones at lunch. Once that leveled off they realized that fights in class got even more views because it involved a teacher. It got to the point where my kid would walk outside to go to their next class because the halls were just filled with kids trying to do anything to get views on TikTok.
The larger issue were the second and third order effects this caused. Kids started refusing to go to school because of the fights and attendance problems soared. Multiple classes were constantly disrupted. Due to the layout of the school most of the hallways are narrow so it was near impossible to get to class on time.
It took the spring break and major intervention from the administration, staff, and students to finally have the fad die out. It still flared up from time to time in the spring, but never as bad as the winter.
This year it's now about how funky of a combination of socks and crocs you can post to Instagram.
