What is "the godhead"

[wil]

The question primarily is for those who use the term regularly.

What is "the godhead"? As in what does it mean to you when you use it? And if you could cite the scripture that is used to define it.

This is open to anyone in any religion that uses the term.

I don't use the term, and anyone I've asked when they do has not helped me to differentiate that term.
