What should I call my alter ego?!?

I decided that I want an alter ego.I know its weird but I thought it would be really fun.. I want this alter ego to be someone who is not afraid to say whats on his mind, someone who can look at someone in the eye through a whole conversation, someone who wont care what people think. Spontaneous, funny, crazy, charming. The problem is I have NO idea what to call Jim hahaha. Any good names? If that's my alter ego, then the personality that I have now..is that an alter ego too? Everyone should make an alter ego hahaha!! I'm kind of shy now and so my alter ego is going to be the complete opposite of me. (: Fun.. What should I call him?
