«زَيِّ الدِّلْوْ»

The expression mocks a dull, sluggish person who never takes the first step or settles anything alone. Like a bucket, such a person stays put until someone else picks them up and moves them from place to place.

The insult targets both missing initiative and missing awareness. The comparison rests only on how a bucket goes wherever it is carried: the person follows others' direction, as an object would, without grasping why or forming any intention of their own.

Use it to mock someone who sits idle until pushed, then moves only as directed. Because it attacks intelligence and initiative, it offends easily when said directly; it belongs in blunt criticism of a passive helper, employee, or relative, not polite talk.
