Guaraní people
The Querandí were one of the Het peoples, indigenous South Americans who lived in the Pampas area of Argentina; specifically, they were the eastern Didiuhet. The name Querandí was given by the Guaraní people, as they would consume animal fat in their daily diet. Thus, Querandí means "men with fat". They were also well known as the Pampas prior to the 19th Century. Mapuche (or araucanos) called them Puelche.
