The unusual etymology of Des Moines, Iowa

The literal translation may be "shit-faced," as explained in the Des Moines Register:

Michael McCafferty, a visiting lecturer at Indiana University who has spent decades researching Algonquian languages, agrees with the commonly held notion that the "Moines" in Des Moines is a French derivation of Moingoana, an Indian tribe that once lived along the banks of the Des Moines River.

But he insists that rather than denoting the tribe's true identity, the name was a ribald joke offered up to French explorers Marquette and Jolliet in 1673 as a bit of razzing between competing Indian communities...

McCafferty based his conclusion on the work of another linguist, David Costa, who wrote an article on the etymology of a number of Miami-Illinois tribal names, Moingoana among them. Moingoana, McCafferty cites Costa, originates from the word "mooyiinkweena" -which translates, politely, to "the excrement-faces."

I learned this from a recent podcast of No Such Thing as a Fish (whose website seems to have no such thing as a search box...)
