You hate beauty, or people who are beautiful (the most beautiful person I have ever met was named Livia hence the name of the word) in a way you wish you were them so instead of wishing you were them you hate them.
Pajama casual is a term used when working from home and preparing for a video conference. All business above the waist and your pajama pants down below.
We have a Zoom meeting in a few minutes and I’ll probably go pajama casual.
