The defining characteristic of male friendships. It is the event when men bully each other in a semi-serious, semi-joking, upfront, and purely verbal manner. When bros brolly each other, they usually pick on a very esoteric character trait of the brolly target so that only themselves know they are brollying each other, and to the outsiders it seems like bullying.
