When you're coming and the chick is kneeling and spins in a circle underneath you, such that you create a cir-cum-ference on her body.

After she went down on my last night, I gave her not just a pearl necklace but a full circumference!

A longer name for the perimeter of, or distance around, a circleโit is the product of pi and the diameter of the circle.

One useful application of circumference is to determine the age of certain trees: the age of a tree is related to the number of its rings and its circumference.
