Definition
A frenzy is a burst of wild, unrestrained energy — activity so excited or agitated that reason drops away. Shoppers in a buying frenzy, a media frenzy around a scandal, a frenzy of last-minute work: in each, normal limits give way to something frantic and contagious. The word suggests a temporary fever of the crowd or the mind, intense while it lasts and exhausting once it passes, when the frantic motion finally burns itself out and calm returns.
