The Mannequin Challenge was a viral internet phenomenon that surged in popularity in late 2016, credited to students at Edward H. White High School in Jacksonville, Florida. The trend involved groups of people remaining perfectly still in elaborate poses, mimicking mannequins, while a camera panned through the scene, typically set to the song 'Black Beatles' by Rae Sremmurd. It quickly transcended high school hallways to include celebrities, professional sports teams, and even figures at the White House. Beyond the video format, the meme persists as a template for 'frozen moments,' used to satirize awkward social situations or instances where a group is collectively stunned into silence. It remains a nostalgic touchstone of mid-2010s internet culture, representing a peak era of collaborative social media challenges.
