What the heck is a "girl girl"?
A 'girl girl' is a female that is overly feminine. And I mean overly. Because of Tifa's...assests, she is defined as a girl girl. A non-girl girl char. would be one who does not display any of the sexist attributes applied to women by the opposite sex. Such as; a non girl girl char would be slim, not well endowed (interfers with fighting), very strong, takes a hit and doesn't even notice it or just keeps on going, extremely skilled in chosen art of warfare, very fast, and so on and so on. And most of all a non-girl girl is not blond or in any way unintelligant.
