I normally write in that annoyingly plain and chatty way that grow up with blogging and involves saying 'stuff' a lot. But, for some reason, possibly overexposure to the Book of Common Prayer, I do this...
"Polysyndeton is, in a nutshell, the overuse of conjunctions. It can give an emphatic sense of grandeur to a bare list of things, however. The King James Version of the Bible is full of it, as witness Genesis I, 26: ‘And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth.’ The opposite of asyndeton."
Apparently it's called polysyndeton.
