Cap'n Insano is a male or female who is so batshit nuts that they are the Captain on their own personal ship of fools (which consists solely of themselves).
"Darla went beserkers on me for drinking her last Yoohoo. That bitch is full-on Cap'n Insano!"
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.
