NOUN: A cart barrier is when you place your cart (aka ball sack) in a woman mouths and the woman then proceeds to craftfully and carefully use her tongue to create a barrier between the
two testicles in her mouth, creating a barrier. Commonly practiced in the midwestern portion of United States.
Part of this process is called "breaking the cart barrier". In order to achieve the breaking of the cart barrier the following must happen. While the ball sack is still in the woman's mouth, the woman must use both
free hands to stimulate the penis AND the prostate. Upon climax the male should release the contents of his cart (
semen) onto the woman's hair. Once this is all accomplished
the man can declare that he has
broken the cart barrier.
