A quick look online shows that the word Exus can have meaning in Latin. Here it can be translated as burn down or set on fire. Google Translate suggests hath burnt.
Digging a little deeper provides a link that connects Exus (in Portuguese) with the Orisha, an elemental spirit of the Yoruba people's of West Africa. The indigenous Yoruba religion is practised wherever West Africans have settled in the world, but particularly in South America, Brazil, Cuba, the Caribbean - all places that would have seen a major influx of Yoruba beliefs courtesy of that thing called slavery.
Of course, the national language of Brazil is Portuguese and so it would be natural for the language of slaves to morph into the prevalent tongue. Brazil, and other countries in Sth America played an important role in the slave trade, and many of those poor souls who found themselves as chattel in this part of the world ended up in forced migrations to North America.
Perhaps there is a distant association, one that crossed the Atlantic centuries ago with the African tribes people who were sold into slavery, that links the trek of the Exus with the journey of the spirit God Orisha.
Then again, perhaps not!
