Mari Lwyd is a Welsh Christmas tradition in were one takes a horse skull on a stick and wraps themselves in a typically white sheet, sometimes the skull is decorated. It and it's party of caretakers go around houses rhyming to be let in, while the people of the house must make excuses in rhyme to why they can't come in. If you surrender, the party gets to raid your pantry and beer.
If it's a Christmas, why am I posting it now? Well, funny horse skull go spooky. And mine's a bit different to fit the Halloween mood!
"So, if you ever find yourself rap battling a horse skull in South Wales, don't panic. It's normal, I guess." -Sam O'Nella
