The rolling tumbleweed has long been a stock sound in western films and animated cartoons, where a dry plant blowing across a deserted town instantly signals that nobody is around. That shorthand carried over to television comedy and then to online video, where creators use the same brief rustling roll to punctuate silence without saying a word. Because the image is so widely recognised, it still works in short clips, reaction videos, and edits that need an instant visual joke about emptiness, waiting, or a moment falling flat.
