It means that an individual believes he is entitled to have whatever he want when he want it, without regard to what is fair or reasonable to others. So he takes everything and everyone for granted. He expects to receive favours without ever having to do anyone else a favour. He feels entitled to invade and trespass on others’ boundaries; believes that everything he receives is his due.
He has no concern or respect for the rights of others but vigorously protects his own. Rules, guidelines, convention and laws apply to other people and he alone is entitled to disregard them. Often he projects an image of arrogance, inconsiderateness and selfishness.
