What should my YouTube username be? - 1

Okay so I've decided I want to make a YouTube Channel and I've come up with ideas for the intro and what games I'd play and all of that… Except for the name. I was thinking something like "Teen____" (something to fill in blank) but I can't think of anything. Here are a bunch of fact about me if it helps…
1. Favorite Color?
Either red, grey/gray, blue, or black
2. Gender?
Female (which I've realized is gonna be a setback)
3. Where do you live?
New York, USA
4. Sports/Hobbies
Karate, Cheerleading, Flute
5. What games or type of game will you make?
I know I will do Minecraft, Skyrim, Escapists, Sims 4 (once it comes out on Xbox One), and as far as type of games I guess Adventure games and every now and then I would like to do some horror games
6. Do you know any other languages and what are they?
Yes. I know a little bit of French, Spanish, Latin, and Korean, and I take German as a language in school
7. What do you like in your free time?
Anything outdoors, games, or hanging with friends
8. Favorite animal?
Wolf

As I made the questions I've realized it probably DOSENT help what so ever but if it did great.

I wouldn't use "Teen" because you won't be a teen forever, and it's very possible that you will still be making videos into your 20s or even 30s. I'm in my 40s and I make videos.

I don't know why being female would be a setback. I wish there were more females doing video game playthroughs on Youtube. Both of my daughters love video games and like watching Youtube videos about them, and they're always complaining that "it's all guys." Even my husband was trying to find videos by women the other day, for a game he's playing - he thinks they have an interesting perspective.

Anyway, for a name, you've got to have something unique because a lot of names are already taken, and also so it will be memorable. Look at what other popular Youtubers use: Markiplier, Tobuscus, Jack Septiceye, iHasCupquake, etc. The names are weird, and about 3-4 syllables long. You might try something like WhistleWolf, Karatechopgirl, Pompomama, Flutenstein, Rottspieler (Red Player) - just brainstorm anything and everything about yourself and combine the words in weird ways until something seems right.
