A reference for girl-on-girl sex where two girls and/or women slam each others' vaginas together in a violent raging fury. This act is mostly performed by the lesbians which are a group of people that like to ride large motorcycles and are usually overweight with unusually short hair that like to revolt people by making out in public at a coffee shop in mid-morning while others watch in horror.
"Dude check those girls out. They are sooo cunt clapping."
It is said of the situation where a person has the bad luck to make contact with his testicles against an undefined surface or object, intentioned or not.
Given the nature of the word, it is more appropriate to design cases where the interaction is made with a moving object, for example, a ball.
Although it is extremely painful for the victim, it tends to be considerably funny to people who witness it.
