«مَا لِكْ يَا خَايْبَهْ بِتِتْعَلَّقِي فِي الْحِبَال الدَّايْبَهْ؟»

Though grammatically addressed to a woman, the saying applies to anyone of any gender. It mocks a person of poor judgment and worse luck who grabs whatever support is nearest, even when it is plainly decayed. A rope that is already coming apart cannot bear any weight, so holding on to it ends in a fall.

In practice the image targets someone who pursues goals through weak, unreliable means or keeps feeding on hopes that are bound to disappoint. The tone is impatient and reproachful, urging the listener to see that such supports will give way.

Say this as a scolding to someone, or about someone, who keeps trusting a flimsy plan, an unreliable person or an empty promise, when failure is easy to foresee. Aimed directly at a person, the rebuke can sound belittling, so it suits moments when such bluntness is acceptable.
