no this is an accurate description of all those assholes who think they're entitled to whatever they want at the drop of a hat from girls they fancy when they show them a hint of kindness. Nice guys are just nice guys.
No no, you don't understand. The description of "friendzoned nice guys" is, in my opinion, what you just described. Yes, they're whiny assholes who think they're entitled to sex from a girl just for doing her a little favor. There is nothing nice about that, because they value the intimacy of the girl as much as a tiny favor like opening a door, and those guys are not nice people at all. What I meant by this is that they call themselves "nice guys" because they think that the reason for not getting the sex they think they're entitled to is being "too nice", but in fact the reason is that there is another guy who not only does more for the girl, but for her is also more pleasant to be with in terms of conversation, looks, interests...for them, he's an "asshole". What they don't realize is that they are the asshole and that guy is just a guy.
That is different from nice guys, as in actually nice people. "Nice guys" are just entitled idiots.
