The airhorn has been a staple of live sports arenas for decades, used to fire up crowds during timeouts and big defensive stands. In basketball culture it became shorthand for hype, especially after made threes and highlight dunks. As user-made soundboards grew in the 2010s, the clean isolated horn became one of the most saved clips, because it works without context. This particular three-second version captures that arena energy in a compact form, which is why highlight editors and meme pages still reach for it.
