A man is an adult male human being, a person of the male sex who has grown to adulthood. If a male is not an adult yet they may be called a boy or teen boy instead of a man. With all the man quotes out there you can find a variety of subjects and topics that are related to males. A true man never tries to bully others or pick on those weaker than he is. The real definition of a man is said to be the way that he works and takes care of his family, ensuring that they have everything they want and using a gentle hand when discipline is called for with his children. True men never beat their spouses, and a man who cheats will likely be unfaithful again in the future.
