1.Yo is used the all purpose word. It is used extremely incorrectly in suberbien areas. In citys (for example new york) generally followed by a formal grasping of the hands by entwineing the digit formally reffered to as 'the thumb'. DO this so the palms do not touch so it does not seem gay. Then followed by a chest bump. Then sometimes drugs or money are passed coat to coat.
