When having a one night stand with a young lady. You go back to hers, get naked and in bed. Then you stick it up her 'wrong' hole. When she says 'no' or complains you shout ACCESS DENIED in the manner Wayne from Wayne's World does. You get dressed and leave without adding to the 'conversation'.
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.
