When a man stretches his balls up above the waistline of his pants, and lays them over the fly, forming a belt buckle of ball sack. Normally, the wearer of the IOR belt buckle will hide it with his shirt, go up to unsuspecting people, ask " check out my new belt buckle", and surprise them with testicular goodness. This maneuver is more easily accomplished with older men, as their scrotums are usually saggy and more pliable. Younger men can perform this, but it takes much stretching and conditioning to accomplish, which they may regret later in life.
