The airhorn has long been a staple of sports stadiums, parties and celebrations, where its loud blast signals excitement and draws a crowd's attention. In online culture it became a signature sound of hip-hop DJ drops and meme edits, used to hype a moment, mock a failure or celebrate a win with exaggerated energy. Its popularity endures because the sound is instantly recognisable, needs no explanation and works in almost any short video, from sports highlights and gaming clips to reaction videos and comedy sketches.
