Sounds like a bad omen, right? Well, it is. Chahuiztle is the generic name for some parasites (especially fungi) that infest commercially important crops. The phrase implies that our problems are going from bad to worse and everything will soon go to hell. Some people misspell the phrase as “¡Ya nos cargó el chahuiztle!” which literally means “The chahuiztle is carrying us!” This second phrase is evidently wrong since fungi do not have arms to carry people around. There are, however, some creepy characters that can (metaphorically) carry us to our demise, like the infamous Coco or the Clown
Never contend with one that is foolish, proud, positive, testy, or with a superior, or a clown, in matter of argument.
