What is a good username for YouTube?

I've been to plenty of username generator sites and haven't found a good one. My names is Lauren I just use Kimmy as my username on here because it is my middle name.
I want to become a YouTube gamer and was wondering what a good username would be.
I'm a huge nerd
I'm also kinda a hipster
I love drawing singing and playing video games
I'm 13
I'm funny
I love adventure time and minecraft
I want it to be kinda a funny yet odd name.
I was thinking Laurenthenerd but that just seems stupid. Like I said I've been to plenty of websites. And none of the names have been that good.
Any suggestions for me?
