It's a tale as old as time: We see a lot of people wearing/doing/saying something and we want to try it, too. Back in the day it was saying "Bloody Mary" into a mirror at slumber parties. Today, it means viral social media stunts. Though adults get caught up, too, kids are especially susceptible to peer pressure and FOMO (fear of missing out). To them, what was once a double-dog dare is now a popular YouTuber eating a hot pepper just to see what happens.
