AirDrop is Apple's wireless sharing feature, first introduced for Mac in 2011 and later widely used on iPhone and iPad for sending photos, videos and files between nearby devices. Its short notification tone became a daily sound for millions of users, so it quickly moved beyond tutorials into memes and edited videos. Online, creators borrow the chime as shorthand for instant sharing, teleporting an object, or delivering a joke to someone else's screen, which keeps the sound recognisable even outside Apple product videos and explainers.
