The sound comes from Five Nights at Bonnie's House, a fan made horror title inspired by Five Nights at Freddy's and centred on Bonnie the animatronic rabbit. In the game the sting plays when an anomaly or animatronic catches the player, copying the sudden scream format that made the original series famous on YouTube and streaming clips. Short recordings of the scare were later shared as standalone effects, and editors began reusing the scream outside the game for horror edits, fake trailers and reaction cuts where an immediate fright was needed.
