man boy

(n) A male who, by age, should be a man, but still acts childish, is oblivious of what acting grown-up is about. An insult to point out ridiculous immaturity. A pathetic example of taking responsibility or manhood. Man-boy clues: You are over 25, not in school and... still live with parents (excluding illness or tragedy), still twist your friends nipples on a daily basis, buy toys off ebay for yourself, think "picking up chicks" is all in strategy of a well-delivered pick-up line, use status or lie about what you do to impress women, have a child and are still out partying like you are in high school while trying to pick up much younger girls.
