The slap challenge is apparently related to the viral TikTok trend called “devious licks,” in which children across the U.S. posted TikTok videos of themselves vandalizing school property. Sandburg Middle School in Glendora was among two schools in the Glendora Unified School District that have faced destruction last month because of the social media challenge, with soap dispensers ripped off and bathrooms covered in some sort of red liquid. This month’s challenge has teacher groups and school districts around the country alarmed, with many issuing warnings to school communities.
