Subway Surfers memes typically refer to the trend of using the mobile game's high-speed gameplay as a background visual for TikToks and YouTube Shorts. This phenomenon, often labeled as 'brain rot' or 'sludge content,' involves splitting the screen between a primary video and the endless runner gameplay to maintain the viewer's attention. While the game has been a mobile staple since 2012, its second life as a meme highlights the internet's shrinking attention spans and the need for constant visual stimulation. It is now widely used to mock content that is perceived as 'unwatchable' without a side-by-side distraction or to parody modern social media consumption habits.
