single word requests - Is there a better name for this than "emphatic and"?

In semi-poetic writing, I have had occasion to deviate from the standard prose list practice (interpose commas or semicolons between items, with an "and" preceding the final item), by utilizing a second or third and to separate three or four items. That is,

Bob likes beer, wine and liquor.

The variant would be:

Bob likes beer and wine and liquor.

Now, the usage is obviously nonstandard and should be avoided in formal writing, but for those instances where poetic variation may be justified.

What is it called?

"Emphatic And" is the best I can coin on my own, but I wonder if there is a more established name for this variation.

Answer

It's called polysyndeton, and creates a polysyndetic co-ordination.

Polysyndeton is the use of several conjunctions in close succession, especially where some might be omitted (as in "he ran and jumped and laughed for joy"). The word "polysyndeton" comes from the Greek "poly-", meaning "many," and "syndeton", meaning "bound together with". It is a stylistic scheme used to achieve a variety of effects: it can increase the rhythm of prose, speed or slow its pace, convey solemnity or even ecstasy and childlike exuberance. Another common use of polysyndeton is to create a sense of being overwhelmed, or in fact directly overwhelm the audience by using conjunctions, rather than commas, leaving little room for a reader to breathe.

The opposite, leaving out every conjunction, is called asyndeton.
