Need help with gaming clan name

Hey guys, I am making a clan for me and my friends to start out with (we'll slowly have more people join if we take it serious) but we want a good name. FSU was my orig. idea but FSUClan on youtube is taken. Yeah forgot to mention, we'll be posting stuff on youtube.
So, requirements:
1. 3-4 letters (like M40, FaZe, although if it's longer but awesome I'd still like to hear it)
2. Isn't already used by antoher clan on youtube.
BTW, I'm going to be gone for the next week so just post ideas here please. I know it's kind of a lot to ask, but please guys help!
