Dude, there are lots of things I might not know, but this is an easy one: I’ve heard that cheer at UL since at least the late 70’s. I also have some good friends that went to refineryville at the same time so I spent many weekends hanging with them during that same time. Trust me, there was nothing ‘cajun’ there but a bunch of haughty kids making fun of our accents. Their lagniappe days were called ‘Jam-Jam.’
I first heard them stealing the cheer around the mid/late 80’s after being ‘Cajun’ suddenly became cool. This was also the same time they stole ‘GEAUX’….and around the same time that that fake-Cajun cook on pbs became popular, the one who a lot of people thought was so funny.
