What would be a good rap name that i could use?

I need help tryin to find a good rap name that i could use to go by? My name's Peter but people call me Pete or Petey and right now i go by the name Pistol Petey but im debating on getting another name to use or just keeping the one i have now? For those who dont know Im white, i live in the hood , and no matter where i go or who i meet people always end up calling me B-Rabbit , or saying i remind them of Eminem alot. I guess the name just sticks for some reason........Can somebody give me some good examples to use?
