SCP-173 is one of the most recognizable characters from the SCP Foundation, a collaborative online horror fiction project that began in the late 2000s. Sounds like this concrete grind are commonly used in fan videos, gaming clips, and meme edits to represent its sudden movement and heavy, statue-like presence. The effect remains popular because it communicates danger immediately, even without showing the creature. It also overlaps with the broader language of horror sound design, much like a scream meme or other abrupt stinger effects used for shock cuts.
