manchild depends on who is saying it. when a man says it, he is jealous the other man has no responsibilities.  when a girl says it, she is mad/jealous he wont settle down and has no responsibilities.  look at all the young actors who got rich young, they stayed young and manchild for life. only aging/stress/full time will age you and turn you into a man. notice how as men age, they turn manlier? well, stress accelerates that too.  man = stressed out, married to a roastie.  also, 90% of men are beta males and are worthless outside of betabuxing providing. so think carefully about who is making the accusation of you being a manchild.
