well, i'm not a woman so you'd be better placed to know, but i always thought it was something to do with the fact that every woman gets hit on every single day and the way to stand out from the dorks is to avoid doing the same thing as them.
Yeah, who wants to be "horny dickhead #26" to some harassed girl? mind you, I know fellas who go through dozens of knockbacks, but eventually do meet somebody that likes them, so I suppose that's the logic there.
My ignoring of girls is not a pickup technique anyway, just a way of trying not to look too uncool while being very shy.
