The Duncan glass break circulates online as a short standalone soundboard clip rather than as a longer scene, which is why it works as a reusable reaction. At under two seconds it can be dropped into edits without trimming, and its clear start and end make syncing easy. It spread through meme edits, gaming videos and short-form posts where creators needed a universal signal for breakage without showing the damage. It remains popular because the meaning is instant across languages and needs no context beyond the smash itself.
