Shacking someone's chinn
With your hand .
Its usely done by placing your hand very delicately on someone's chinn an then spontaneous schaking it around while using a lot of strength and momentum.

Not to be confused with a chinn lay where someone intensionally lays his or hers chinn in one's hand.
The other person wil then shake it around and thank the person for overing his or hers chin

Boy: hey let's give him a chinn gripp because he did a silly face

Girl: yeah of course I always stand for justice
