call him something with a very good significate, not for the others, for you, so every time you read your name in the screen you will think "thats a nice name", that is why im called Black Tears, everybody thinks that is emo or deepy, but it has a completely diferent sense to me
Also is always good to use popular or famous names: Nixon, Adolf Hitler, Fidel Castro....or even Don Quijote, Felix the cat.
Or call it something from your country, i would like to name my rapist sneaky-burster "tlaxcalteca" unfortunately there isnt enough space

But never i mean NEVER call it something like the names of the guys in the forum, youll be shoted down as soon as you find people. or lols names like thelul, d1ck, merapeyou, i kill everybody wearing idiot names.
