Corneta is the Portuguese and Spanish word for a horn or bugle, and handheld air horns have long been used at football stadiums, parties and street celebrations to signal goals and excitement. Online, that same piercing blast was clipped and shared as a reusable sound effect for edits, remixes and prank videos. Its stadium roots explain why it instantly reads as celebration, alarm and chaos at once, which is why creators still reach for it when a reaction needs to be loud, sudden and unmistakably over the top.
