What does "grazer" mean? How did it come about?

The content is as follows:

There is a family on the hilltop at the junction of Nanxi and Yueqing. The father-in-law does not have a mother-in-law, and the bride does not have a husband. The father-in-law has a strong back and is busy working in the fields every day; the bride, tender and tender-eyed, goes to bed every night to guard the empty house.

On normal days and when it rains, the father-in-law lights the fire and the bride makes noodles; the bride washes her feet and the father-in-law ladles soup. You told me not to burn it well, you grabbed the tongs and rubbed your legs, your eyes were smiling and your face was red, and your buttocks turned up, which made me panic; I told you not to burn the soup, and you squawked over the spoon, your teeth were exposed, and kowtowed to hurt your legs. Hold a pair. The two of them looked up and looked down, flirting with each other, gradually forgetting their identities, coughing and peeing in the middle of the night, that kind of thing.

The farming season is here and the millet is about to go to the fields. The bride got up early in the morning, without her coat on, with her arms and legs exposed, and cooked food for her father-in-law. Burning, burning, thinking, scratching the ashes of the kitchen stove with the head of the tongs, I heard the door of the father-in-law's room, and ran into the bathroom shyly. The father-in-law here has already seen her in his eyes, and it touches his heart. He had eaten the egg wine she made with noodles in two bites. He wanted to pick up some firewood ashes from the stove and take them to the fields to spread seedlings. When he looked down, he saw a line on the ashes:

The father-in-law has no wife or slaves. Husband,

My father-in-law is my husband during the day and my husband at night!

The father-in-law stood up angrily, and turned around to push open the bride's door...

As soon as this incident spread, some people began to call the father-in-law "the gray picker".
