Its a pretty good username.
BTW, you are not alone. The same story happened with me, my previous username was Coolboy12 and I wanted to change it to 'Asad'. Unfortunately, it was taken so I had to go with CB Bhallu TC (inspired from Shary Bhallu TC) and then for some reason I could not log in to Pakgamers for some time and when I came back, the option had ended.
SO I was stuck with this.
