What does stealing farmers mean in StarCraft? Beginners hope you don't laugh.

There are two explanations. At 1. P clan is azazel's third skill. 2. In the Z clan, when you become the ninth farmer, you use a farmer to make a gas mine, so you lose a population, and then you can become a farmer. In this way, only the upper limit of 9 people is 10 farmers, which is called stealing a farmer.
