doucheosphere 

When someone who is a douchebag experiences the delusion that not only is he not simply a disposable, usless bags of douche who does not assist in the functioning of the planet in any way, but also that he is important enough to actually be a planet, and he begins orbiting his own douchey self.

We could tell he was really living within his own doucheosphere when he tried to sue his ex for dumping his sorry ass.
