Brother you need to die.

If he's doing that stuff then the chances are somebody is doing it to him at school. Like other people have said, relataliate because even if he does start to hit you back he will just realise that you won't let him get away with it and might stop.

My brothers the same, but apart from the smoking.. dude its just what they do. I punched my brother accedently in the face and gave him a black eye, he is still annoying but not as much.

I just want to ask if he's older or younger.
Personally I dont have younger brothers and sisters but I have a nephew.
He's often like that to me, im jumped on spat at kicked but its often
because something at school is anooying him or my sister doesnt spend time with him.
Often theres a reason if not bribe him with money or lollies to leave you alone

Same thing. I got a younger brother and he acts top ...., but fact of the matter is that he isnt. He insults me and tries to prove he is the more dominant one over us though im not even competing.

Sooo.....

If hes younger, do what I do, when parents are gone simply walk into his room while hes there, punch him a bunch of times and smash his stuff infront of him for added affects.

If hes older, Revenge. Simply trash his room, I dont mean break a glass or something. Throw tv's, computers, burn some things, break windows. Now of course he will get revenge on you by doing something back, but if he does... just smash his stuff again and again and again and evidentially he will stop out of fear for his belongings.
If your parents get mad, state they didnt help in the first place.

My friend did that, his brother broke his computer trying to show off to some friends, so he lit his bed/xbox360 on fire. He got no blame cause it was revenge and his parents said his brother deserved it for beating up on him.

Though your parents might not be that nice.

Siblings can get annoying at times, but you just have to bare with it. Sometimes I wish I never had my sister, but then again I think of all the good times we've had together and I love her so much. Your brother will grow up eventually, and these things won't happen. Wishing him dead doesn't help at all.
