Quad cheek clap

when your girl is super fine and you are clapping cheeks, to your neighbors, its a sound that breaks the sound barrier, its what you would call "quad cheek clap." If you haven't clapped cheeks like this, you are not living life.

It sounded like a QUAD CHEEK CLAP, not a sonic boom.
She has the ass that can QUAD CHEEK CLAP.
Nigger boy Ill eat your ass and slap them cheeks, call it a QUAD CHEEK CLAP
