Mega horns have long been used at sporting events, rallies and celebrations to make noise that carries across a crowd, and recordings of that blast have become a staple sound effect online. Creators reuse the short, attention-grabbing blast because it needs no explanation and works in almost any language. It appears in sports edits, reaction videos, prank clips and meme compilations, where a single blast can turn an ordinary moment into a celebration or a joke. Its simplicity and instant recognisability keep it in regular rotation for short-form video.
