A man by age but a child in mentality and actions. Usually an inability to get over the "frat boy" or "party boy" phase. Can't have fun without a beer; oftentimes brews his own beer. Still relate to women as sex objects (even in they're married) and are emotionally undeveloped (e.g., fight for their rights mentality even if there is nothing worth fighting; rarely takes responsibility for own failings). A general irritant to women and men that have matured.

A man child is a male who is over the age of 25, who still lives as though he is a juvenile. Many man-children are not gainfully employed, and survive off of the financial support of their enabling parents. Heavy video-game addiction to fantasy games such as World of Warcraft are key to the man-child.
"You'll never believe it, but that 30-year old uber-gamer man child who lives door to me finally got a job!"

A young teen with the ability to grow facial hair, that other people the same age can't. Also the facial hair has to be able to look like a full grown man could have grown it. This type of person is able to get attention for looking older than he really is.
That person looks like a man child. I wonder how old he is because he looks older than his teen years.
