A pretty simple one. I had dream that there was a craze for parmesan-infused sparkling mineral water, and everyone was obsessed with the stuff. I didn’t like it, and was considered extremely uncool. You could buy it pre-packaged, but a lot of people became obsessed with making their own by soaking parmesan shavings overnight, and would leave a few bits in the bottom as a status symbol so people knew what they were drinking. Here is a quick photoshop mockup of expensive cheese piss-water.
