I’m pretty sure they just didn’t want to say Orange Julius. That was the big brand at the time, and it was amazing. Looks like they are still around, but I don’t know if they have been enshittified. www.orangejulius.com/en-us/

It was just a frothy orangey creamy cold drink - not icy like a slurpee or icee, just very cold and frothy. Somehow amazing.
