Originated in Cincinnati, Ohio in the Fall of 2005, oso machino was the name of a traditional Klotterian folk band. The name soon evolved into a life affirming statement, insipired by the Klotterian band's attitude, used in times of stress and discontent. Many have compared the phrase to hakuna matata however, oso machino is often used in a much more abrasive manner.
