Entertaiment means something that entertains you in a way that makes you forget your problems and wish the experience never ends. It could be anything from a movie, a concert, a game of football or just spending time with your friends. Entertainment can make you feel in a euphoria state and forget all your worries but it should not hurt people or be below their dignity.
