Coil Head is one of the hostile creatures in Lethal Company, the cooperative horror game released in 2023 in which players scavenge abandoned moons while avoiding monsters. The creature only moves when it is not being watched, so its sound became closely linked with sudden danger and players being caught off guard. Clips of encounters spread through gameplay videos, streams and short-form edits, where the noise was reused to surprise viewers outside the game itself. It remains popular because it instantly signals a Lethal Company moment and works as a quick, recognisable prank cue.
