Castenitis 

A disease that transforms you into a North American Yeti. A North American Yeti is a harry all over except for the head, which is bald. They live in North America (duh!) and really like the Chicago Bears. They also argue a lot, and are ill tempered. They have bad manners, and will closeline you as well if they get angry, using their over developed forearms.

"Damn, I got Castenitis, there goes my social lfe"

"Call National Geographic, I found someone with Castenitis"

Castonitis 

The urge to cast on (or start) many different projects all at the same time.

"Casting on" is a term used in knitting, when starting a new project, one would "cast on a new project"

"Itis" is used with reference to a tendency or state of mind that is compared to a disease. "creditcarditis"

Thus Knitter's have begun to use the word "Castonitis" when the urge to start many different projects at once hits them.

"After seeing all the knitted socks you've made, I've got a serious case of Castonitis!"
