The Spanish cimarrón means "rough", "brute", or "barbarian", but is most widely understood to mean "feral", and is used in almost all of Latin America for domesticated animals that have become wild. The word was then used by the people who colonized the region of the Río de la Plata to describe the natives' rough and sour drink, drunk with no other ingredient to sweeten the taste.
