Your probably asking yourself wtf does this mean, the answer is nothing. Your friend probably made a typo. As an example ill repeat what my ex said to me.
"you never really opened up to me or talked about how your feelings igtifm"
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.
