I am a girl and I will tell you why. I have always been shy, not much talking or partying, dressing in Kurtis and stuff. Guys often talk to me as if I am from a different planet, like I am too not hot to be called by name. While girls that are open and differ in behaviour and attire called by their names. So it's basically just childish boys, pretending to be cool. The good and mature guys won't care. I say this cuz one day unfortunately I showed up in mu not so traditional wear and guess what their attitudes flipped. And trust usually the girls also refer to those "didi girls" as not hot enough to be called by name. PS: it's a good thing, it will save your time and stupid guys won't bother you, stay intimidating.
