Stupid adult child! (Small rant)

My brother is 24 and he still lives with me and our parents. He doesn't drive or work. He doesn't pay rent or pay for anything. Also he's a vegetarian so that he will lose weight yet he still eats junk food... He sits on his butt every day on his computer. He does not wash himself and he has long tangled up hair. You can smell him when he walks into the room thats how nasty he smells. He also never washes or changes his clothes. One time he had a shirt that he wore every day with no wash for a few years and it just kept getting a bigger and bigger hole in it until you could see his man boobs. He pees all over the toilet seat with no regard and let's his curly hair get stuck to the pee and dry. Now the toilet is stained from it thanks a lot. He only recently learned how to cook for himself and now he gets up at 4-6 am to cook. 4-6 AM TO COOK?? I can smell the smoke from my room every time he cooks something there is smoke! He complains about everything and he's a smartass. I want him to move out.
