Free range kid
Like a free-range chicken, but for a child that is not giving boundaries or rules or consequences from their parents or society.
Look at that (Frange,bock bock) free range kid, he can do whatever he wants and curses and not getting in trouble because his parents and society believes that he will find his own way. he needs consequences he'll never learn... He is like a free range chicken, bock bock here! bock bock there!
