(Katkootah is a cutesy way of saying katkoot, which means chick and comes from the katkat cheeping sound they make, and is also used to describe someone cute [feminine], katkoot being the male equivalent. Sghanoonah is a very cutesy diminutive of sagheerah / small, little one... shibr wu nus is an exaggerated description of someone being very tiny, it literally means shibr: the span between the thumb and little finger, an ancient Arabic unit of measure... and a half. Shibr and a half. xD)
