Grammelot (or gromalot[1]) is a style of language used in satirical theatre, a gibberish with macaronic and onomatopoeic elements, used in association with mime and mimicry. The satirical use of such a format may date back to the 16th century commedia dell'arte; the group of cognate terms appears to belong to the 20th century.
While the historical origin of the term is unclear, it has been particularly popularized by the Nobel-winning Italian playwright Dario Fo with his 1969 show Mistero Buffo.
