A man with the character of a young child. Also could be a juvenile who is too young to be old, but too old to be young. An old soul trapped in the body of an adolescent. A man who is too old for babysitting, but desperately needs it.
"Her boyfriend, Darren, is a complete and total man child. I'd offer to babysit it, but it's kind of creepy."

A man who has a mommy complex like no other. He is extremely needy and will want a woman to "take care of his needs" eg. satisfy his insatiable thirst for chocolate milk, tucking him into bed at night, packing a lunch for him etc...
Johnny was such a manchild he made Julie put on his socks in the morning.

A term originating from Claude Brown's 1965 memoir "Man-Child in the Promised Land" about growing up in the streets of 1940s and 50s Harlem, NYC, one of the earliest and most powerful accounts of ghetto life and its culture. A "Man-Child" originally referred to a boy or adolescent from the streets who was prematurely exposed to and knowledgeable about sex, violence and crime, incarceration, adult responsibility for younger siblings due to a dysfunctional home, and hustling to make a living.
You think life in the 'hood is rough now? Check out Brown's book one day. By the time he was 15 he'd already been locked up, hustling for a living and doing whatever he had to to survive as a man-child on the streets.

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.
Facebooking about brewing beer and gross bodily functions is typical of a man child.
