This sound is mainly known online as a reusable meme impact effect rather than a clearly credited clip from a specific film, show, or game. It spread through short-form edits on Instagram, reels compilations, and meme videos where creators needed a fast, simple hit to underline a visual beat. Its popularity comes from how flexible it is: the thud can make a reaction look heavier, make a cut feel sharper, or give a joke a dry, sudden finish similar to a shocked sound.
