“'n Boer maak 'n plan” is a South African phrase that translates to "a farmer makes a plan". It's often used to describe creative and determined logistical solutions. For example, a moving company might use the phrase to describe a system they created to move large items out of a house without damaging the walls or furniture.
The word “Boer” is Dutch for “farmer”. The Boers were a group of white people who emigrated to South Africa, mainly from Holland. They were skilled in guerrilla warfare, but eventually surrendered to the British in 1902. The descendants of the Boers are called Afrikaners, and today they make up over half of South Africa's white population.
