A supercut is a genre of video editing consisting of a montage of short clips with the same theme. The theme may be an action, a scene, a word or phrase, an object, a gesture, or a cliché or trope. The technique has its roots in film and television and is related to vidding. The montage obsessively isolates a single element from its source or sources. It is sometimes used to create a satirical or comic effect or to collapse a long and complex narrative into a brief summary.
