I saw kids doing this on concrete recently. On concrete.
Tiktok is literally an at-scale sorority/fraternity, which means people are taking part in an at-scale hazing ritual - to fit in. The problem with this is the same problem that arises if you are 20 and watch Sesame Street every day still. There’s a time and place for this behavior and we are not setting any cut offs for when it’s time to stop the nonsense.
