Definition from Wiktionary, the free dictionary
- (South Africa) Settlements with shacks made of wood, cardboard, tin and other scrap material. Whole families live in a single shack, the size of a garden shed. Open fires are used for cooking and candles for light - shacks often catch fire when there are accidents. There is no running water, sewerage pipes, gas or electricity.
