Prounce is the act of intentional flirting. It is the combination of pouncing and prancing. It is gracefully going in for the kill. It is usually a feminine verb. One can "prounce", be "prounced", go "prouncing" and one can be a "prouncer"
Dude, that chick was totally prouncing on him.
Woah, what a prouncer.
