Emptytarian
An emptytarian is someone that has entered a major grocery store and found only empty shelves where food once was, resolving to change their dietary habits to conform to the new reality. It matters not whether this new reality is due to pandemic-induced supply chain problems, a zombie apocalypse, or a sudden rash of fanta pants. For those that had been vegetarians, vegans, fruititarians, and carnivores, the sight of so many empty shelves can convert them to becoming an emptytarian.
The store shelves appear empty but they are actually selling dreams, aspirations, desires, and lots of hot air that's all bottled up. I for one have one have stopped being a Vegan and become a Emptytarian!
