When you are partying with your drug of choice but you dont want anyone to know what it is, you just say im feyocing.
What are you doing? Oh im feyocing tonight. Oh really so am I. The person you tell that to knows but nobody else does so you can use it in public with nobody knowing but the person you are telling.
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.
