What “The Real-World” really mean...to you?

If you think this is a stupid question, please share with me why do you thing so.

I would want to collect thoughts about what "The Real-World" means to you.

My aim is to grasp if there is a sensible use of the phrase or it is just another way people get fuzzy when just don’t know how to explain something.

I think often the phrase comes to mind as another way to say:

"A recurring situation with perceivably insurmountable constrains"

Or

"A perceivably conventional understanding shared by more than one person on more than one location in the same frame of time and context"

Here are more:

"The practical world as opposed to the academic world"

"The set of real or hypothetical causes and effects that simulation technology attempts to replicate"
