The phrase comes from It's Been So Long, a 2014 fan song by The Living Tombstone inspired by Five Nights at Freddy's 2. It tells the story from a mother's perspective while naming the game's child murderer, William Afton, long depicted by fans as the Purple Guy. The lyric turned into a meme in 2020, paired with Afton edits and the line I always come back. The instrumental theme was clipped separately and spread on soundboards as shorthand for a lurking, remorseless killer.
