How would we know it? You would only know it if you were out hitting on women, got a shit test, didn't back down, and then broke through with real flirtation followed by a hookup. Or if you at least witnessed that in person. I had a friend in college who had a way with doing this. He wasn't into PUA whatsoever, just didn't get phased by what girls said. I can't "prove" this to you, though, so you don't have to believe me.
Legit. ITs almost like many girls test to see if you think ure on their level - and if they see u think u are, then they also think u are.
If u pussy out, well then they got confirmed u really dont believe ure worth her, hence ure a pussy anyway.
