It's about when stuff like nukular bombs or yellow cakeget spread around by evil doers.
"Yeah, I've thought about nukular perif-perifu... waitasec... nukular perifulation... whatever. It's hard. But I know it's a bad thing. It's a really bad thing, and it's just not good for the American people. And I'm gonna make damned sure Iraq stops doin' it, before it comes over here in the form of a big hairy mushroom cloud." --George W. Bush
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.
