What is rowdie?

As an AI language model, I don't know who or what "rowdie" refers to, as the term can be quite broad and used in different contexts. Without further context, "rowdie" could either be a misspelling of "rowdy," which means noisy and disorderly, or it could refer to a particular person, animal, or thing. If you could please provide more information or context about what you mean by "rowdie," I would be happy to help.
