Some sports radio guy down there stole it from the Bengals. The Bengals have been using "Who Da" for quite a few years. Since people from NO speak fun when they say "Who Da" it comes out as "Who Dat".
I still think it will be the Vikings and the Chargers in the superbowl. Keep in mind I am a Colts fan, but I am realistic. SD is playing very good right now, and the Vikings "D" is much better than NO.
I respectfully disagree on both accounts.
Ahem...
"The "Who Dat?" Cheer
"Who Dat" became part of a chant for fans cheering on their favorite team. It has been debated exactly where it started, but some claim it began with Southern University fans either in the late 1960's or early 70's and went "Who dat say dey gonna beat dem Jags" - Southern University being nicknamed the Jaguars. Another claim is that around the same time it began at St. Augustine High School, a historically African-American all boys Catholic high school in New Orleans, and then spread to the New Orleans Public Schools. Another claim is that the cheer originated at Patterson High School in Patterson, Louisiana (home of Saints running back Dalton Hilliard). In the late 70's fans at Louisiana State University picked up on the cheer. In 1983, the New Orleans Saints organization adopted it during the tenure of coach Bum Phillips,
though fans had been cheering the "Who Dat?" cheer since the team's inception in 1967. In 1981, the Cincinnati Bengals fans and players started with the now famous "Who Dey" cheer."
Silly Bengals fans. It started in Louisiana, and continues....

As far as the Vikings being superior, I think they'll drop a game or two along the way, and there's NO WAY they go to the Superdome and beat the Saints.
