Its a comedy movie and is based on what happens in real life. How the boys are humming around girls. And the one not in relationship are more independent and tension free then one in a relationship.
This movie shows how boys who were alone got into a relationship and after getting fed up with the girls habbits and their different excuses they decide to all breakup and be back to where they were. So I recommend you to watch this awesome movie and rate it 5 stars because this movie has simply nailed it.
