This clip is associated with Backrooms content, an internet horror concept that grew online from liminal space imagery and creature lore. Sounds like this spread through short horror edits, found footage videos and meme compilations, where creators needed a fast audio cue for an entity appearing nearby. Its staying power comes from how quickly it establishes dread without explanation. In practice, it fills a similar role to the X files cue in mystery edits or a shocking sting in sudden reveal videos.
