An effort to be inconspicuous when scratching one's scrotum. A scrote roll is a very fast, very effective way to stop an itching sensation by grasping the itchy area with the thumb and forefinger, and sliding them in opposite directions, thus creating a rolling effect.
Hey Roger, 3 scrote rolls in one hour? You totally have crotch crickets.
