Five Nights at Freddy's is the 2014 indie horror game created by Scott Cawthon, where a night security guard survives by monitoring cameras and closing two office doors against roaming animatronics. The door sound became one of its most recognisable cues because players heard it constantly under pressure, tied directly to the draining power meter. As the series grew into a major franchise, clips and soundboard copies of the effect spread into fan games, edits and meme videos, where the slam alone now signals a hasty, defensive escape.
