in this video jessie j is singing about that she can do everything that a boy can do. The background dancers help to show this by dressing like boys, smoking cigars, getting tatoos and dancing like boys. they also gamble, hang around in gang like groups and have short hair. the cinematography used in this video is mainly fast cuts/ scene changes. they used low angle shots which make the singer look more powerful like they have control over the viewer. they also use close ups as that displays emotion. and in this occasion it displays here as angry as men are portrayed as more angry than women.
