Kinkly explains Balls Out

The phrase “balls out” actually does not derive from the testicles being exposed to danger. It goes back to the days of steam engines. The speed of Watt style steam engines was controlled by a centrifugal governor. At fast speeds, the balls of the centrifugal governer would rise out. At full speed, these balls would be completely out. Thus, the term “balls out” was born.
