«لَا لِلْبِيتْ وَلَا لِلْغِيطْ»

The proverb sets two basic spheres of work against each other, the household and the farm, and declares that the person in question fits neither. It condemns someone as unfit for any task, a person from whom no help or benefit can reasonably be expected.

The same verdict can fall on an object. A tool, possession, or arrangement that serves no purpose at home or in the field is written off as worthless.

Use it to dismiss someone judged incapable of contributing anywhere, or an object that serves no practical end. A blunt verdict after repeated disappointment, it can wound when aimed at a specific person, so it suits frank, informal talk rather than polite settings.
