Goal horns have long been part of NHL home games, sounding after the home team scores to fire up the crowd, and Pittsburgh's version is closely tied to the Penguins at PPG Paints Arena. Clips of the horn spread through fan videos, game highlights and social media edits, where it became shorthand for a Penguins goal even for viewers who never attended a game. It remains popular because it is instantly recognisable to hockey fans and carries the energy of a live arena moment into short videos, streams and reaction clips.
