The 'Death Knocking on Doors' meme, also known as the 'Grim Reaper Door' meme, features an illustration by artist J.L. Westover from his Mr. Lovenstein comic series. The image depicts the Grim Reaper leaving a trail of blood behind three open doors while knocking on a fourth, symbolizing the inevitable downfall or 'death' of a specific entity. Since its emergence around 2013, the meme has been widely used to comment on business closures, the elimination of teams in sports tournaments, or the decline of social media platforms. Its power lies in its sequential storytelling, allowing users to build a narrative of destruction before revealing the next victim in the Reaper's path.
