Black area in the pubic area which can be seen through the clothing on a person, usually wearing light colored swimwear. Most often seen on women wearing white, yellow, light blue or pink swimwear. Most often the nest is not visible until the clothing is wet.
If she wants to continue to wear that white swimsuit in public she needs to really think about shaving off all her pubic hair so we don't all have to see her cooter spider nest.
When a woman uses a beverage coozie specifically to stop from freezing her vagina when holding a beer between her legs, the coozie is called a cooter protector.
Yikes! This beer is cold! Don't y'all have a cooter protector I can slip on it to keep from freezing my cooter?
