Post-Shift is a Five Nights at Freddy's fan game series, and its Custom Night modes let players face variant animatronics including Twisted Springtrap. This clip comes from that setting, labelled as a Twisted Springtrap scream, and circulates among fans who collect every FNAF jumpscare scream variant from official and fan games. Short scare sounds like this stay popular because they are instantly recognisable to horror game players, easy to drop into edits, and effective even without the original gameplay footage for context.
