In the film the Amitabh Bachhan character sings the song in a nightclub while pinching an expensive diamond necklace off the neck of the beautiful posh girl he is dancing with, all the while thwarting the designs of the girl's original dance partner (Amjad Khan) who had set out to do the same thing himself. The song is a series of boasts about his own prowess at sleight of hand and taunts directed at the rival thief.
