Geometry Dash is a rhythm-based platform game released by RobTop Games in 2013, in which players guide a cube through obstacle-filled levels timed to music. The death sound is one of its core gameplay effects, heard whenever a run ends after hitting an obstacle. As gameplay clips, speedruns and challenge videos spread on YouTube and TikTok, the sound became instantly recognisable even to people who had never played the game. It remains popular because it packs a whole failed attempt into less than a second.
