urban legend

an incredible or lurid story, often involving a mixture of horror and humor, that is widely repeated as if true (often as the experience of a “friend of a friend”) but can never be firmly documented. Urban legends differ from myths and folktales in that they nearly always have a contemporary setting and often involve modern technology (e.g., the many such tales about microwave ovens).
