Casagande

A new word has entered the Family Dictionary...casagande and it may seem so, but it isn't Spanish. The Boy has made up this word. He uses it in response to questions he doesn't know the answer to or in resposne to questions he doesn't want to answer. A couple examples:

Me: Why don't you want to stay in your bed?
The Boy:Casagande
Me: Why is that over there?
The Boy: Casagande

I asked The Boy what casagande means and he says it means casagande. Now I know.
