I know they when people use the term "nice guy" here they generally mean "nice" in the psychologically manipulative. PUA sense of the word.

When I first thought of the term, I thought of it in the genuine sense of being courteous and polite as opposed to overly confident, artificially charming, pushy or cocky.

It's sad to see that people assume that someone being "nice" is not genuinely nice for the sake of it.

I know you can't charm a woman into wanting you after she's already rejected you. Anyway that's my opinion.
