Literally just beat his fucking ass when he's hammered you fucking pussy, I'm an alcoholic who lives with my mom and brother, and that's what my brother did to me. You'll feel better and he'll learn a real lesson about how drinking turns him into a defenseless pussy.

>legal issues

90% chance the police will literally not give a shit as long as you don't just straight up admit to assaulting him.

My brother is a pussy, I am not, and he still mustered the nerve to fight me when I was weakened, do it OP
