Old wives' tale
(重定向自Bubbe meise)
Old wives tale is an epithet used to indicate that a supposed truth is actually a superstition or something untrue, to be ridiculed. It can be said sometimes to be a type of urban legend, said to be passed down by older women to a younger generation. Such "tales" are considered superstition, folklore or unverified claims with exaggerated and/or inaccurate details. Old wives' tales often center on women's traditional concerns, such as pregnancy, puberty, social relations, health, herbalism and nutrition.
