Yes. for foeigners it is correct. translated loosely as outsiders.. Remember here languages change ever 100+km as well as nomenclature of daily use words not to mention the accents.
The joke we have here is... who is not an outsider including my fellow countrymen. I am 3rd gen here.
you need to travel upland. Take a drive up north via N1 to Kimberley then on via Potchefstroom on to Mafikeng; then left to Zeerust. That is where I am.
Will be in South Africa in July for my honeymoon. Landing in Joburg and then flying to Cape Town. Plan on doing some touring this time
