First coined by XKCD webcomic. This pertains to when you stumble upon someone on the internet whose beliefs and allegations are so wrong, it creates an unstoppable urge to correct them.
This urge can so strong, your earthly concerns (hygiene,eating,sleeping,etc.) are tossed to the side until either the issue is resolved or you just collapse from exhaustion.
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.
