What's a Y'at?

What's a Y'at, you ask?

From Wikipedia:

Y'at refers to a unique collection of dialects of English spoken in New Orleans, Louisiana. The term also refers to those people who speak with a Y'at accent. The name comes from the common use amongst said people of the greeting, "Where y'at?" (Where you at?), which is a way of asking, "How are you?" While the term Y'at is usually reserved specifically for the strongest varieties of the New Orleans dialect within the city, the term often refers specifically to speakers of Y'at, outside of the city proper, and around the rest of Louisiana.
