I think that the name for the Zacachichimenca and for the recently executed uncle is an interesting thing… namely the use of the word dog as a pejorative.
I have always been intrigued by the almost cross-cultural use of the word in this way. The thing is, most of the world does something like this with one word or another.
Once I called a friend a worm, with the intent being more in the glory of the being but they took great offense. While I maintained (to their disbelief) that it was well intentioned the truth was that it was not a term that spoke to them in a way they understood. I assume they got over it.
But, as a species that loves hierarchy it is interesting to ponder what thing a culture can perceive to be as low enough to be an insult.
