Mari Lwyd, the scariest Christmas tradition
Every culture has its own way of celebrating Christmas. While most people sing carols and make snowmen, Welsh people are used to seeing a person with a horse skull come to their doors and sing rhymes. They call it Mari Lwyd. Although its costume is creepy, the situation itself sounds a bit amusing.
According to the tradition, you have to get into a rap battle with the Mari Lwyd. You sing rhymes and tell them they shouldn’t enter your house, and they try to convince you to let them in. If you give up the battle, the person in the costume drinks all of your beer and leaves afterward.
