Smoke and mirrors is a metaphor for a deceptive, fraudulent or insubstantial explanation or description. The source of the name is based on magicians' illusions, where magicians make objects appear or disappear by extending or retracting mirrors amid a confusing burst of smoke. The expression may have a connotation of virtuosity or cleverness in carrying out such a deception. (wiki)
