From the "57 Varieties" slogan used by the H. J. Heinz Company
- (of a thing) A complete mix; containing parts of many different origins.
- (of a person or animal, chiefly a dog, informal) Having ancestry of many different origins; to be of mixed race or breed
1995, Erika Bourguignon, “Identity and the Constant Self”, The Psychoanalytic Study of Society, volume 19, page 183:
- “[...] My mother is a bit more on the Heinz 57 side. She's got a strong Germanic background, a little bit of British, and my maternal grandmother is French-Canadian.”
