The Vine Thud, also known as the Vine Boom Sound Effect, is a bass-heavy percussion sound that originated on the now-defunct Vine platform. Initially used as a dramatic transition or a punchline emphasis, it has become a staple of '21st-century humor' and surrealist internet culture. The sound is often paired with specific visual cues, most notably Dwayne 'The Rock' Johnson performing his signature eyebrow raise. It serves to amplify the awkwardness, shock, or comedic timing of a scene, often being spammed repeatedly in fast-paced video edits to create a sense of chaotic irony and mock-seriousness.
