In trying to explain my joke I think I found it may not directly apply outside of the Arabic speaking Arab world, but typically last names are important as they say who the person is the son or daughter of https://en.wikipedia.org/wiki/Arabic_name?wprov=sfti1#Ism

It isn’t just a lineage of last names but who your daddy is.

If I remember correctly from my Arabic class in college some people can have even longer lineage names with multiple peoples included.

Pakistan seems to be sort of a mix https://en.wikipedia.org/wiki/Pakistani_name?wprov=sfti1#Full_name

I also found this random paper describing Afghani naming so I wonder if I was wrong. https://citeseerx.ist.psu.edu/document?repid=rep1&type=pdf&doi=e7a649988b7aad015ea8fa972239c7fe9e6ede03
