Beauty Guru Youtube User Name Ideas?

I'm 12, turning 13 in less than 5 months, My name is McKenna. KennaBoo, Kenna, and Boo are my nicknames, and I want to become a beauty guru on Youtube. I have a lot of makeup, I know some cool tricks and hairstyles and some cute nail designs I would like to make some tutorials for. But when it comes to user names I have no clue. It does not have to do with beauty, but It can. I honestly don't care. I'm just so stumped and can't think of a user name! So any suggestions are highly appreciated! Thanks! [:
