On a forum here someone had started a thread on "~~~ish ~~~ are called just ~~~ in ~~~" - the initial thing being spanish villages, which are called just villages in Spain. Then the spanish walls - just walls. Then hungarian notation (which I would take as an insult if I was hungarian) would be called just notation in Hungary...
You can imagine all kinds of things that were listed. The last addition, which appeared to me when one daughter came back from a trip to Egypt and another from having her bones set: in Cairo, they call them just practors.
