The title supports all of this in that, in truth, the line from Shakespeare's play, "Romeo & Juliet" - "...Then I defy you, stars!" is literally saying that he defys fate and defys his destiny, which back then, was supposed to be foretold in the stars. Therefore, in this particular song with these lyrics, the subject is defying their own fate, and defying their own destiny -which was to become one of the mindless "mannequins" by whom they're surrounded.
another side-note I forgot to mention
