Chair movement sounds like this one are a staple of everyday sound effect libraries, where a brief scrape is used to sell a simple physical action without dialogue or music. Creators reuse the same kind of clip across comedy sketches, vlogs, animations and short-form videos because the noise is instantly understood in any language. At under a second long, it works as a punctuation mark rather than a background layer, marking a shift in posture or attention. Its popularity comes from that usefulness, not from a single viral moment.
