The midwinter majesty of THE MARI LWYD Mari is taken around a village traditionally, often between Christmas Day and Twelfth Night, She is dressed with festive lights and decorations, and is usually accompanied by an ostler. When the group gets to a house, they sing Welsh language songs or wassails, or more traditionally indulge in a ritual called pwnco: an exchange of rude rhymes with the person who lives there. https://www.wales.com/about/culture/mari-lwyd Mari Lwyd
