What are some of the characteristics of an urban legend?

Urban legends are typically modern folktales that are passed down through Word of mouth and often feature sensational or supernatural elements. They usually involve a narrative that is relatable and taps into common fears or social anxieties. These stories often claim to be true, despite lacking verifiable evidence, and can vary in detail with each retelling. Additionally, urban legends often carry a moral or cautionary message, serving to reinforce social norms or behaviors.
