"Viveza criolla" is Spanish language phrase literally meaning "creole vivacity" and may be translated as "creoles' cleverness" or "creoles cunning". It describes a way of life in Argentina, Uruguay, Colombia, Ecuador, Peru and Venezuela, among other Latin American countries. It is also known as "criollada" in Peru.
It is a philosophy of progress along the line of least resistance, ignoring rules, and a lack of sense of responsibility and consideration for others. It extends to all social groups and throughout the entirety of society. In Argentina, it is predominantly associated with Buenos Aires and its inhabitants, the porteños. Viveza criolla has been called "the principal cause of a moral, cultural, economic, social and political crisis".
