I started using this at work (in a hospital) we can't say 'quiet' or 'slow' as it brings the Thunder, so I started using Dick-all. This means nothing going on, no business, no plans, boring. Also see 'Jack-Squat'.
"There is dick-all happening in the OB unittonight" or "let's do something Friday, I have dick-all for plans".
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.
