I'm angry at my brothers pc addiction
Why would you be angry about your brother's PC addiction?
He has many times. He depends on his computer when he should be with the family, he eats up all the food when I'm not there to stop him, he talks my mom into buying him stuff after stuff which also costs a lot of money, he puts in long hours at night when I try to sleep in my own room, he shuts me in when I want to use the computer. And he talks every single word with every damn food item in his mouth when I make food for him
It makes sense that you are upset with your brother for acting like this. Your brothers pc addition is directly affecting your life as well and is causing him to not even care about how he is coming across to other people. Do your best to let him know that and also tell your parents so you can try and get some sort of change.
My brother is a selfish prick. I'm gonna smack him one day.
Even if your brother is selfish, you shouldn't hit him. Try to find alternative ways of dealing with him.
