showing off. stuntin'.

comes from the imagery of showing off your grill. you bare your teeth as if you were in front of a mirror flossing. thus showing off your grill came to be known as flossing and flossing came to mean showing off in general

flossin 

To present oneself in the most attractive (and perhaps most ostentatious) possible manner. Typically entails driving a convertible, sporting jewelry, wearing fashionable clothing, and properly grooming oneself (i.e. one may go to such an extreme as to practice a rarely witnessed form of dental hygiene).
