n. extreme anxiety; nervous hysteria. (Old. One might call this vintage literary mock colloquial, since it survives in the works of well-known writers and occasional literary use. The origin is unknown, but the Oxford English Dictionary lists Fantad with the same meaning, and cautiously suggests that is related to fantasy and similar words containing fan.) The afternoon’s excitement has left Lady Waddington with a case of the screaming fantods. The reviewer felt that any slang dictionary that excluded “fantods” was defective.
