I have a problem. Every 1 says I'm good at beat boxing its tru. And started think about having a nikname, I didn't tell anyone though. I waz thinkin' about dj ,but I don't know how get my friends to call mii that can you help me?

I'm sure that you are good at beat boxing but when getting a nickname it is given, not something you give yourself. I'm surprised your friends haven't gave you one already.
I'm sure your friends all have a nickname, just asked them if they ever had a nickname for you that best describes you beat box ability.
