Friday night. 'Frinight' should be used instead of saying Fri-day-night, because like saying 'mmm this cookie is cold-warm', that's really stupid. Also, Saturnight etc...
Person A: "Hey what are you doing Frinight?"
Person B: "Probably just staying in and orderin a Hot n Ready"
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.
