An boy aged between 12 and 16 whose face has outgrown his body during adolescence, resulting in the awkward imbalance of having a man's face on a boy's body. Man children are invariably no taller than 5'7'' and are sometimes (not exclusively) afflicted with severe acne which extends to the chest and back. Man children are usually quiet and shy in social situations.
Person 1: "hey quick look across the road there's a man child, a real goodin"

Person 2: "Mate, wicked man child spot! Why do you reckon they always wear cargo shorts?"

Person 1: "Hmm?"
