A rebellion against walking in someone else's shadow, the shadow of someone who thinks the singer is stupid. The person being sung about would seem to be a lady, so there may be something of a domineering effect being felt by the singer and the rebellion is against that - he is sick and tired of walking in someone else's shadow, so he is saying they can do it for a change and find out what its like there out of the limelight and being subordinate.
