If you were around in the summer of 1966 and you tasted one of the very first SLURPEES, you might have said something like "Right On" or "Far Out" or "Groovy". 50-years-ago, that's how something great was described. Flash forward to 2016. Taste a SLURPEE today and it's like: "Boss" or "Legit". Same idea; different vocabulary. The hair has changed. And the clothes. And the language. But it's 50 summers later, and SLURPEE is still SLURPEE. Still the first. Still the favourite. Still the best.
From baby-boomers to Gen Zs, about the only thing that hasn't changed is SLURPEE. Because you just can't top the original. It was cool in '66. It's just as cool today.
