I would call it creative. It is not something anybody would normally say. But it makes sense, so who cares if you're the only one to say it?
An Italian friend of mine once said, speaking of a friend who had just found a girlfriend, how pleased he was that "his friend had found a new company". To him, it sounded normal because he was translating from the Italian. In English though, it sounded so odd. And yet, ... so sweet. I really liked it. Don't be afraid to talk in uncommon ways.
