Similar to OMG (Oh my god!), but ending with a fashionable "osh" to imply "Oh my gosh!", which isn't "Oh my god!", which is important, if importance was the issue. Which it's not.
The term "omgwthigo" is an acronym that stands for "Oh my gosh what the heck is going on?!" normally used when the person either truly is clueless on what is happening (usually wherever the other person is communicationg from) or as an expression while in a confusing online conversation, mostly with more than two people involved.
The longer version is more explicit, and self explanatory on what it is
"omfgwtfhifgo"

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.
