Shannonism is a religion followed by those who believe that everything in the world can be understood through the laws of Information Theory, postulated by Claude E. Shannon in 1948.

"Shan said that the Office is coming back tomorrow, I called shannanigans. I was right."
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.
