Teacher Flirting With STUDENTS?!?!?!?

My computer science teacher has always been kind of wierd. He failed every girl in my cl last quarter. He specifically always accuses me and my friend all the TIME! Like today he was explining what corcth was its some kind of tool I know I spelled it wrong! Well im in 8th grade and people thought it was funny because he said they are long and pinty and also squishy. My cl has a sick mind lol. So the WHOLE cl started laughing but he specifically tell me and my friend to stay in the hallway. One day my teacher was fighting with my friend and she kept talking back because she was being falsly accused. He literally rose up his arm about to hit her. Every1 thought he was about to hit her. He looses me and my friends prjects ALL the time on purpose so he can fail us. I stay after school and work hard for what? to fail me! Since we have a firewall and we were learning HTML I wanted to added a video from the youtube on a bridge and he said we could requests sites. Then I said never
