Brat advice

My girlfriend and I are long distance and I’m a brat. Since I can’t be a brat in person we mostly just tease on call. I need advice on things I can say, because she told me she wasn’t gonna get creative with punishments till I got more creative with how I tease her. I usually just tell her I’m in charge, what are you gonna do about it, you can’t do anything, I’m so powerful, etc. any brats with advice?
