crazy about, be

crazy about, be

Also, be mad about. Be immoderately fond of or infatuated with, as in I'm crazy about lobster, or George is mad about his new saxophone. The first expression dates from the early 1900s. The second, with mad, is much older; Shakespeare had it as mad for in All's Well That Ends Well (5:3): "madde for her"; and mad about was common by the mid-1700s.
