The 'Slap a Teacher Challenge' emerged as a highly controversial and largely rumored TikTok trend in late 2021, following the 'Devious Licks' craze. It allegedly encouraged students to strike their educators on camera, sparking widespread concern among school districts, law enforcement, and parents across the United States. While many reports suggested the challenge was more of an urban legend or a localized prank rather than a widespread movement, it became a significant cultural flashpoint. In the meme world, it is often used to satirize the perceived absurdity and escalating danger of viral social media challenges, frequently appearing in 'What's next?' style templates to highlight the chaotic nature of internet trends.
