The story of the film is that the hero doesn't want to live a regular, 'boring' life, and looks for a 'kick' in everything, something that keeps him high instead of being bored by things. Here in the song the same reference has been used and the girl says that she doesn't get a 'kick' without him. He is needed for her to be high.
The song, composed by Yo Yo Honey Singh and Jasmine Sandlas, features Salman with Nargis Fakhri, and is called 'The Devil Song'.
