I'm sure this was happening in the sense that you can find any brand of niche crazy if you go looking for it but the "teens getting 'Tourette's'" was a bigger thing and absolutely fascinating. Writing it off as just kids faking it for attention you miss the really cool phenomenon that you can pick up tics like like any other accent's quirks. And just like accents unlearning it is an annoyingly hard process once those brain pathways form.

So they didn't have Tourette's and they weren't faking it, but a seriously cool third thing. Monkey see monkey do is a powerful phenomenon. We just treat it as normal when it happens as part of socialization.
