The term given to a sausage used to prevent the juice from baked beans touching a fried egg. Obviously only to be used for people who don't like the two items of food mixed (unlike me).

Invented by Alan Partidge, who said that his Russian wife made a good fried breakfast, good, but not brilliant, because she doesn't use the sausage as a barrier.
"Ah, no, I didn't get a barrier in my fry-up!"
Recorded on a pen microphone: "The barrier."

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.
"Guys so get this. Good News. My girlfriend and I finally broke the cart barrier today. Her hair was such a mess afterwords."
