Teens: What kind of accent do you have?

I have a British accent, but ever since I moved to the states my "American" accent has been improving a little. Like for instance I still say "Mum" but I also catch myself sometimes saying "Mom" too. I guess you can say I have two accents at once! lol. My parents accents though are heavily british, but me and my siblings accents are just about Americanized. lol
