Air horns were originally used as loud signaling devices on boats, trucks and at sporting events, where a single blast could cut through crowd noise. Online, the short sampled version became a staple of prank videos, gaming edits and meme compilations in the 2010s, often layered over reactions for exaggerated celebration or mock alarm. Its brevity makes it easy to reuse, and the familiar stadium association helps viewers instantly read the moment as rowdy, funny or deliberately over the top.
