To make ones butt cheaks clap together. It's a new phenomena which can mostly only be done by a chickwit a big ass. It's accomplished by abruptly bouncin dat ass but, like I said it's almost impossible unless you got a whole lotta ass.
an action wich usually happens during the act of intercorse. the clap is caused by the mans pelvis rapidly contacting the butox of their partner in such a way that it causes a claping sound.
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
