I have noticed that some Spanish people actually use Spanglish on purpose, mostly as a joke. One of these type of expressions is: “mother mine” which is the direct translation of “Madre mia”. I have even heard famous people on Spanish television saying “mother mine!!!”
So then I started thinking: “How do you say “Madre mia” in English?
The answer is: “Oh my God!”
Hope that helps!
