To say something deeply underwhelming in a profound way and immediately following the statement with a melodramatic gesture; not unlike how in all the show's opening scenes, CSI: Miami's lead character Horatio Caine (played by David Caruso) usually makes an anticlimactic statement, slowly slides his aviator sunglasses on, and looks off into the distance.
That guy is always Horatio-Caining any chance he gets! He's always waiting for the right moment to drop a single sentence he's been sitting on all class and then to slowly take off his glasses and stare out the window.
