Hello Neighbor is a stealth horror game developed by Dynamic Pixels and published by tinyBuild in 2017, built around sneaking into the house of your suspicious neighbor, Mr. Peterson. Its chase moments became one of the most recognisable parts of playthroughs on YouTube and streaming clips, where the sudden music told viewers a run had gone wrong. Fans began lifting that cue for edits and memes outside the game, and it remains popular because the panic it signals is instantly understood by anyone who knows the series.
