POPGOES is a fan-made Five Nights at Freddy's game released in 2016, built around new animatronics including Simon, a key voice heard as the nights progress. Night 4 raises the pressure, and Simon's lines became a recognisable part of that late-game atmosphere for players sharing clips online. The sound spread through FNAF fangame communities, edits and soundboards alongside the classic FNAF jumpscare scream, and it remains used because it instantly signals POPGOES rather than the main series, giving fan videos a specific, nostalgic horror identity.
