When a person, usually a guy, but girls have them too, hasn't shaved their face and it looks like they have dirt above their lip. Sometimes girls bleech theirs. Mexican children usually have them. James has one. Thats where the name originated.
I'm glad Adam shaved his Jamestache before banquet. He looks better. I wish Jen would realize hers and bleach it.
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.
