Can I ask you something a bit off-topic? In Spanish (well, specifically in what you've heard in Mexico) do people use the word Jesus like you just did (i.e. Jesus esto es horrible)? Or is there a similar word/phrase that you would say takes that place?
I'm from Spain and there it's only used when someone sneezes.
The word "Jesús" is rarely used nowadays to express a strong emotion like astonishment or disgust. It's something my grandparents would have said. My father is in his 60s and sometimes says it but only jokingly.
It's more common in Mexico but it's also disappearing. When someone sneezes the usual response is "salud".
