If you really hate him then go for an all out mauling!!! Absolutely kill him!!!!! First go for a kick to the shins to take him down or use some judo. Then its sometimes a nice touch to kick him "where the sun don't shine" to teach him some respect. You can choose to stop there or you can keep going and punch him in the face and stomach. If you absolutely loathe him go for a vicious kick to the kidneys right in the hip area on the side of his torso but be careful this move will put him in extreme pain and if you think he can't take it don't try it because he might get really hurt.This is the trickiest part....Getting away with it. You could try going elsewhere and maybe listening to some music or doing homework to trick you parents. I hate my brother more probably more than you do and I have used this method many times and I am 11 and he is 15. Works every time. HAPPY MAULING
Beat up your brother and you are liable to have your mother and father down on you like a ton of bricks. In comparison he might suddenly seem very nice.
very carefully!!! as the answer before me points out you may end up on the wrong side of the deal with your parents... if it helps then hit him where it hurts like right in the pocket, by telling him if he gives you a dime or a dollar then you'll be square... Other wise I would take the other answers advice, and not get on the bad side of your parents thoughts and trust... Good luck
Kill him! I'm in the same situation EXCEPT my bro is 3, and I'm 12.
