Ways to piss of my moms boyfriend?

My moms boyfriends is a real douchebag. She has had 3 boyfriends since my dad left and all of them were alright but this one is extremely bad. He gets in me and my siblings faces and yells at us. he accuses me of lying all the time even when i am not because i am a teenager. he hates my little bro (10) and me (16) for some unknown reason but he loves my little sister (7). Im real tired of him. Ive told my extended family stories about him. They all cant believe it. He called my little bro a dick for not sharing some fries from a restaurant with her. He made me and my bro only clean his and my moms car for 7 hours straight last 4th of july for leaving a popcorn kernel on the counter the night before. it was so bad i had chemical burns from the windex. my little brother is too small to do anything. I am big though so i have choices. Anyways there is alot more stories that are equally if not worse than the ones i mentioned but long story short i hate him. and i hate my mom. please dont answer with answers like "you really should discover the problem with your mom and work with her on it" ok its not like that. my moms boyfriend is here to stay for a looong time and i just want to make his life more difficult. i need your help. me and my bro cant take it. ive been able to run away to my grandparents house for 4 weekends in a row now. i am lucky though. summer is soon though which means i ll have to see them in the daytime too because i wont be in school. can someone please help me?
