Who is the Man's Man? He's the real class act. He always shaves and wears clothes that fit. He's worldly, educated, and a gentleman. He thinks that buttoned shirts are not just for special occasions and that newspapers have more than one section. While he is polite, he is not a pushover. He will swear when he needs to, but will try to control his temper. He can handle his liquor and keeps himself in shape. Most importantly, he will admit his faults and errors, because that is what real men do. He don't have to be gay or straight, black or white, Republic or Democrat, Athiest or Evangelical; he just does what ever he thinks makes himself a good person that he can be proud of. For these reasons, women want him and men want to be him.
2) A man that is macho by default.
NOTE: A Man's man is highly sought after by women who want to feminize him through marriage usually with negative results.
However, the man's man is more a myth than fact. You really can't be a man's man without being a douche bag to others or without having money to throw at things. The sophisticated types of man's men generally have had every opportunity afforded to them by their parents or the equivalent from birth and generally live self diluted facades of a life. the rugged type of man's man generally mooches or takes what they want (possibly stealing) and generally live poor lives.
generally, the man's man is a mask that men put on to seem superior to others.
