I had seen the #zuzai tag on mastodon a few times and had no idea what it was, but discovered a whole site dedicated to the new word. It’s pronounced like “zoo’s eye.” You might say an author uses a zuzai writing process, or a teacher requires a zuzai testing environment. Is it a little pretentious to set up a whole website to justify the weird, new retronym you just came up with in a fit of ennui? Maybe. But I like zuzai, it encapsulates something that currently takes a lot of words to otherwise explain, and I hope it worms its way into the public zeitgeist.
