Also known as ‘vulval lips’. The outer lips are usually fleshy, and the inner lips are usually thin but, like every other part of the body, they come in all shapes and sizes. In some women, the inner lips are completely enclosed by the outer lips. However the inner lips are more sensitive than the out lips.
Can also be used as a greeting.
Walking into a room of people, spotting the bitch and saying "Alrite cunt lips!"
