How to get someone back? NEED BYE TODAY!?

Im 13, my brother and I were sent to clean up the back yard after a party. He acts like he's the king of the house and it annoys the hell out of me!! I want to hit him so hard but i know he'll beat the crap out of me! Anyway, He made me flinch by fake punching me and i said no i didn't and he told me to pick something up and when i came back up he swung at me and i blocked it. Then he hit me in the face with his other hand hard and i wanted to KILL HIM ( not really ;) I knew he would hurt me badly if i hit him back so i locked him out. as i'm writing this he's banging on the windows. How should i get him back? I don't want to snitch because thats stupid, and i don't wanna tell my mom or dad. I want to get him back without hurting him or him hurting me?? NEED BY TODAY PEOPLE!
