The MLB Cardboard Cutout Fans meme captures the bizarre aesthetic of the 2020 professional baseball season, where empty stadiums were filled with static two-dimensional cutouts of people and pets. These 'fans' became an instant internet sensation as viewers noticed hilarious placements, eerie staring contests with the camera, and the occasional casualty when a foul ball took out a cardboard spectator. The meme is typically used to represent a lack of reaction, 'phoning it in,' or being physically present but mentally absent. It serves as a nostalgic yet absurd reminder of the pandemic era's impact on sports culture and the creative ways teams tried to maintain atmosphere.
