On April 21, Liam Weyer, 19, of Kansas, posted a video on TikTok where he dispassionately exclaimed, "Pee your pants challenge," before urinating on himself in front of his bathroom mirror. And just like that, the #peeyourpantschallenge was born. 

Weyer was admittedly surprised to discover that getting people to record themselves as they pissed their pants became a trend because it was created as a joke that was supposed to be a social commentary on the pointlessness of other challenges that have gained widespread attention.
