An exclamation of surprise and, often, happiness. Jeepers creepers, what great news!
An interjection of surprise or delight. The equivalent of “no kidding!” or “wow!” depending on the context, the phrase came from a 1938 popular song first sung by Louis “Sachmo” Armstrong in the movie Going Places. The chorus began, “Jeepers Creepers, where'd ya get those peepers? / Jeepers Creepers, where'd ya get those eyes?”
