Spanish Acronym Pronunciation, Spain Vs. Latin America

I went back to Spain recently for the first time in over 10 years. I was chatting with my buddy Manuel, and he said something quickly that sounded like gobbly gook. I had acclimated myself to the Latin American way of talking. There are differences. That’s one of the reasons I didn’t understand Manuel in Spain. And of course, what he was talking about–it didn’t even exist 10 years ago!
