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!"
Someone with sweet voice that could melt any hearts just by talking. Really cute smile. Tend to be insecure but actually have the face that people would be jealous of.
