The phrase comes from Five Nights at Freddy's, the 2014 indie horror game by Scott Cawthon. In the first game, 'IT'S ME' flashes during rare hallucinations linked to Golden Freddy, becoming one of the series' most recognised lines. As Let's Play videos and fan edits spread online in the mid 2010s, players began isolating the whisper as a standalone scare cue. It remains popular because it signals the animatronics are aware of the player, turning a simple text gag into a lasting horror meme.
