Hair Compensator is a guy who is going bald on top but grows a ponytail in the back. Also grows a massive beard to make up for lack of head hair.
Hey look at pony tail dude. Yeah, what a Hair Compensator...he went bald on top so he is making up for it by growing it long in the back. At least it's better than a comb-over Trump style !
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.
