Who Dey vs Who Dat

[Bobweaver1]

Who Dey was used first by fans. Although "Who Dat" was a term much older, they didn't start using it until they realized how amazing "Who Dey" sounded. I think people recently think we stole it because people were able to watch NFL package and out of market games.
Add to it that we've sucked and the Saints found some success prior to this year.
