What does "ZUUL" mean?

This is by far and away the most frequent question I get asked… so let me set the record straight.

Zuul the Gatekeeper of Gozer is a demigod and minion of Gozer, The Destructor, alongside Vinz Clortho the Keymaster. Zuul is assumed to be female due to being known as The Gatekeeper and for possessing a female host instead of a male host. It possessed Dana Barrett in Ghostbusters. It was worshiped by the Mesopotamians, Sumerians and Hittites in 6000 BC, along with Gozer.

It is of course a Ghostbusters reference, but why? Why not!
