I’m asking about the structure of the expression. If the answer is YES, then what’s the reason for the comma. Besides, which Egypt is meant, “The Arab Republic of Egypt” or that “region of Illinois”, near Chicago?

This is another example of how important the context is to the use of a word or phrase.
The two words are used to indicate not just a far away place but a very far away place. This is most likely to have been used first in the USA so if you live in Africa or the Mediterranean it would not have the same force for you.
The words are used like Town-Name, US-State-Name. This is why the comma, just as in Chicago, Illinois or Baltimore, Maryland. The imaginary town name of b-f is itself an expletive of the most derogatory type. The country of Egypt is generally taken to mean a very remote location and reflects no opinion of Egypt other than ignorance. It has been a frequently used, very crude term to dismiss the origin or current location of a the noun.
