Piercings...?

I've always really wanted to get a piercing but my mom wouldn't let me. She thinks im not "responsible" enough which I am, but I never actually did anything about it. Mostly out of fear of getting yelled at all the time when something even remotely similar is brought up. But I've been thinking what if I get one anyway? I could get my friends parents to sign anything if the piercer needs parental consent since since most of them dont gaf. I would really want angel fangs but they usually dont let yoy get em if you dont have other piercings and theres no way I can hide them. So, I was thinking just get a septum? And do the thing where you push it up so no one can see. I would need to save money for it and maybe give up the free time I have to work as long as I legally can but I think it would be worth it.
