Stop hating on her. God, its none of your business to ask her if they know each other IRL or shes a G.I.R.L just because of some IGN. In runescape I had the ign Adinamos which in Greek meant "Weak" and I was a warrior with 72 str and 68 atk.
The number of G.I.R.L is exaggerated more then it is. Most of the girls I meet is girls irl. Just because the name says something about gender then thats person did not know or just playing? Perhaps we should act like mature kids and not stick with other peoples business.
