I come across that word every now and then, just like most other words that are not super commonly used. I feel like people who say things like this don’t interact much with anything outside of top-level mainstream media. They only know about and watch the most popular things, which are in general pretty dumb things. They only listen to whatever is the newest hit, only watch whatever AAA movie or series is currently being advertised everywhere, they don’t read or engage in anything else.
