My mom wont let me go to the movies with my friends for something i did..?

She was gonna let me go today but she's not letting me go anymore for something i did yesterday. So yesterday morning my moms friends that are girls came over and my mom was in the shower and my sister was asleep. I was awakened by the doorbell so i answered the door but in my boxers. My got mad and came to my room and said why'd you answer the door in your boxers? I said its my house i can wear whatever i want. And she said no you cant. I said yes i can and i just pulled down my boxers. My mom said youre not going to the movies with your friends anymore. So now my mom wont let me go. I asked her if i could go but she said no you cant. She said go ahead and walk around the house naked all day. She said show me that you mean what you say and then maybe i'll let you go. What should i do or say to my mom so she'll let me go?
