A condition where a guy feels he is entitled to dating a girl simply because he has been her friend and let her cry on her shoulder about the jerks. When she is not attracted to him, he choses to blame it on the fact that he has been a "nice guy" and she only wants to date jerks. Really, not the mentality of a guy who is actually nice, because one should not be kind in the hopes of getting a girl and simply be kind for the sake of being kind. Any guy who tries to guilt you into dating him simply because you are friends has the mental affliction known as nice guy syndrome.
"Hey Pam, do you want to date me?"

"Sorry Bill, you're a good guy, but I'm not interested like that."

"You're such a bitch! You won't date me because I've been a good person to you."

"I think you have a case of nice guy syndrome."
