SCP-087 comes from the SCP Foundation collaborative horror project, where SCP-087 is described as an endless, unlit staircase that explorers descend into darkness. The entry was later adapted into a short, free indie horror game in which the player walks down the stairs until a pale, faceless figure suddenly appears, creating the jumpscare that became widely shared. Clips of that moment circulated through gameplay videos and horror soundboards, and creators still use the sound because its abrupt scream instantly signals a classic internet horror scare.
