I found another collection of typical South African words on onceinspired.co.za to add to your SA vocabulary.

Braai
What is a braai? It is the first thing you will be
invited to when you visit South Africa. A braai is a
backyard barbecue and it will take place whatever
the weather. So you will have to go even if it’s
raining like mad. At a braai you will be introduced
to a substance known as mieliepap.

Ag
This is one of the most useful South African words.
Pronounced like the “ach” in the German “achtung”,
it can be used to start a reply when you are asked a
tricky question, as in: “Ag, I don’t know.” Or a
sense of resignation: “Ag OK, I’ll have some more
mieliepap then.” It can stand alone too as a signal
of irritation. Details
