Person 1: hey man are you going to the party this weekend?
Person 2: Yeah, I hope that Jitamus Prime doesn't pull up
Person 1: Yeah man, that dude is always buggin about something
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.
