«يُغُورِ الْفَلَّاحْ بِزْيَارْتُهْ وِحْمَارْتُهْ»

The image is a farmer who calls with a present, but his donkey grazes on the host's food and fouls the yard. The loss far exceeds the gift, so the host bluntly wishes him gone, visit, present and all. The opening is a rude dismissal, not a neutral farewell.

More broadly, the saying targets anyone whose generosity or help is outweighed by the trouble they bring along. Better to receive nothing than pay so dearly for a modest favor. The farmer is only the figure in the image; the saying is no slur on farmers as a class.

Say it wryly about a guest, helper or partner whose small kindnesses come with a larger cost in damage, mess or expense. It fits complaints among people who know each other well and can sound rude if aimed directly at the person.
