New Orleans Saints fandom comes in so many different shapes and forms. The Who Dat Nation is possibly the most diverse and varied group of fans in the NFL. It makes it difficult to answer the question – what is a “Who Dat?” It means so much to so many different people. But the one common denominator is the passion that runs deep, and it’s much more complex than simply saying we are fans of a football team that plays in our city.
The phrase “Who Dat” is an idiom that dates back to the turn of the 20th century.
