"Bra"ing someone is the action to quickly pull down your shirt and expose a vast amount of cleavage and bra. This is most commonly done between two women, but if a boy is lucky enough may happen to them. Can cause mild increase in heart rate, erections, and/or occasionally anger.Keep in mind when about to "bra" someone you must be wearing a bra, and bras may slide down with shirt if not careful.
So I was bra-ing at the bar last night , but I forgot I wasn't wearing a bra!! Well at least I got a free drinks.
