Probably God’s second greatest creation after @The Punjabi Playboy , but when you get to that part of slurpee when you have to start eating it instead of drinking it
I think sno cone and tastee freeze were the originals Slurpee was the first to make the ice with flavour though, the first two were crushed ice with syrup poured over it
Of course, the first were people peeing in snow and putting it in a cup, lol. But it might have been pockets of independent inventions and not one where it spread out from an individual originator.
I love slurpees, especially the funky ones mixed with ice cream. The store by my house in Surrey did those for an extra buck, it was sweet.
