The 'December 22 Incident' refers to a series of viral TikTok slideshows that utilize psychological horror and shock value to unsettle viewers. These memes typically begin with harmless or nostalgic imagery before abruptly transitioning into disturbing, distorted visuals or 'void' aesthetics, often accompanied by eerie audio. The specific date of December 22 became a recurring motif used to create a sense of impending doom or a 'creepypasta' style countdown. It gained massive traction among the TikTok community as a way to prank unsuspecting scrollers, evolving into a broader trope of 'incident' memes that rely on the element of surprise and internet urban legends to generate engagement and mystery.
