or just get real quiet. then out of nowhere hit the biggest guy there in the nose as hard as you can. If you hear a pop youve done well. Next you have to be quick on this. Hit him in the throat as hard as you can. He should start to crumple to the floor. On the way down starting pummeling him in the soft parts of his face. ie nose, jaw. cheeks, eyes. dont punch in the forehead, temple, chin, or skull area, you can break your wrist. This should be done very quick and all the punching with one hand, your power hand. If done correctly the krew should freak out. If not, you will get your ass poned. But hey you will have broken a guys nose, so it might be worth the beating.
