Goal horns and sirens have been part of ice hockey arenas for decades, sounded by the home team whenever it scores to fire up the crowd. Different rinks use different horns, from train style blasts to electronic sirens, but the meaning is always the same. Online, that arena signal escaped the rink and became a shortcut for victory in sports highlights, meme edits, and reaction videos, where creators borrow the crowd energy of a live game without needing any footage from the arena itself.
