The cut-up technique is an aleatory literary technique in which a written text is cut up and rearranged to create a new text. The concept can be traced to the Dadaists of the 1920s, but it was developed and popularized in the 1950s and early 1960s, especially by writer William S. Burroughs. It has since been used in a wide variety of contexts.
