If you're a true playa/pimp/gangsta, you're out on the street busting out the "fo shagginoff" to show you're down with something. It means "for sure", but no way in hell is it the white version of "for sure". All them playas/pimps/gangstas somewhere out west or down south have been using it for centuries; since the beginning of time.
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.
