I feel like upsetting my gf again.
Do you really want to upset your girlfriend?
Yes, I know I'll get in trouble again but I don't care
It seems that you don't have a reason for upsetting your girlfriend. Rather than try to make her mad, you should think of something pleasant you both can do together. This will help to avoid unnecessary tension and drama.
I just want to make her mad, even though she'll be mad at me..
If you keep making her mad you might end up single. Also other people can see the way you treat her and you might get a bad reputation.
