Nousin is a Portmanteau word, or blended word, of the two words Niece/Nephew and Cousin. This is most typically used when the age difference between the Aunt/Uncle and their Niece/Nephew is small in comparison to a more typically observed age gap. Nousins tend to function more like cousins then having a Elder/Younger relationship.
