A man who is to afraid to speak his mind. Often times they will complain about how they are mistreated by women and hate the "Alpha's", "Frat Guy" ,"Athletes" and label them as troglodytes. What the nice guys fail to realize, is they are weak at a fundamental level. They only befriend the girls who are attractive because they have hopes that the friendship will result in sex or relationship. They kling on to these attractive woman because they do not have enough confidence in themselves to say they deserve more and better from these relationships. The pandering fool often is depressed because though he feels that he is close to the girl, he understands fundamentally the woman will not grow to like him. This is because girls are attracted to confidence on a very basic level. The obsequious ways of the nice guy are the embodiment of lack of confidence and self loathing. Nice guys do not strive to be jerks but good men. The difference in the two paradigms is this, nice guys do what they do to receive validation and praise, good men do what they want because they want to. Good men are truthful, honest and blunt.
I was a nice guy and hated myself and the world, I became a good man and I love life and the world.

A term used by a female for a male she does not find sexually interesting.

See also: friend or just a friend
One of life's great mysteries is how women can simultaneously complain about inconsiderate man-whores and the impossibility of finding a "nice guy", while sitting across from a hetero male friend who also has similar male friends that she has met but declined to date.

A male who expects a female to accept his romantic advances simply because he is "nice," and is angered when she does not.

Possible causes for this phenomenon:

1.) He views romance as a prize he is entitled to, like his allowance, as long as he behaves himself.

2.) He thinks all women are the same dainty, smiling, flower-picking Disney princess, who want nothing more in a man than giant smiles, polite chit-chat, poetry readings, and doors held opened for them. He does not understand that women are individuals.

3.) He has a mental disability that encourages girls to put on a super-nice act around him, as they would around a child. He mistakes this for their real personality, and thinks they are really getting to know each other and clicking, when...no. (This one's pretty tragic, and no one's fault, really.)

4.) He's a really bad actor, so even girls who DO want a "nice, sensitive guy" can see right through his crap.

5.) He is a genuinely nice guy, but only goes for hot girls he has nothing in common with...while complaining that girls always go for the "wrong" guy.

6.) A closeted homosexual or transsexual, who has discovered how conveniently the "nice guy" motif can cover up his secret. ("I'm just not a man's man!") This can leave a bad impression on the girl, after she learns the truth. She may become so paranoid, that if the next guy she dates cheats on her with another woman, she may break into a joyful jig, exclaiming, "My boyfriend is straight!"
"I am so finished with dating nice guys! Next time a guy tries to pick me up in a sparkely blue prius, I'm not going on the date."

A man who has rejected the societal notion of masculinity and chosen to define himself from the inside out instead, realising that traits such as empathy and nuturing are not actually limited to the female of the species, and nor are aggression and assertiveness limited to the male.

Despite this newfound revelation, however, there is still a strong genetic predisposition for humans to continuously behave as if we were animals seeking out the alpha male with those genes most suited for surviving in a hostile environment.

Often times, the average woman, whom society encourages to indulge in her weaknesses and surpress her strengths, is a self-loathing masochist who may appreciate the nice guy's friendship and understanding, but feels no attraction toward him because his insecurities remind her of why she hates herself. Therefore, she almost always seeks the dominant, aggressive, unempathic male with whom she can vicariously live to make up for her weaknesses. Of course, this inidividual, commonly known as a jerk, is also usually an egotistical, disloyal, and shallow person for whom societal dictates of masculinity will force him to disregard his mate's feelings and treat her as if she were beneath him.

Feeling emotionally unsatisfied, the female will then turn to her nice guy friend, whom she has long since castrated, for comfort, and complain to him about how men suck, except for him, and that he deserves a good girlfriend eventually except that it is never her or any other woman he might encounter.
