I hate trying to pick good names, takes me up to hours sometimes to find something I like. Just remember when picking a name to make sure you really like it and not something you will be sick of 1 week later.
Me and my friend are Twin Pking and his name is th3b3stn3rd (The Best Nerd) and mine is th3bestgeek (The Best Geek).
Its pretty funny actully, and someone might just think were a bunch of noobs until I appear and gang him.
