Best Hidden Peircings?

So I used to have my Lip peirced had snakebites, Got tired of them and took them out, I had my eyebrow peirced but my mom wasnt to thrilled and made me take it out. I have my ears gauged with double peircings which doesn't look as crazy as everyone says. Id really like to get a hidden piercing that my mom wont take too much of notice too. Like i wanted to get my Clavicle peirced but a friend of mine posted it on facebook and one of our mutual friends got all pissy about it. Which i dont really understand. I do my peircings myself. All of them. And none have gotten infected or anything. So please dont say anything to refrence of me needing to have gone to school for it or need it done professionally. I am a big girl i am just fine. But i would really need a few ideas.(: It would help me out TONS!:))
