Pizazz, to quote the editor of the Harvard Lampoon, is an indefinable dynamic quality, the je ne sais quoi of function; as, for instance, adding Scotch puts the pizazz into a drink. Certain clothes have it, too. 1. There's pizazz in this rust evening coat, swinging wide in back, jutting crazily over the shoulders, clasped with a cord at the throat.
