What does "like water off a duck's back" mean?

Answer by  lea (68)

It means that water rolls right off a duck's back, and that whatever was said or happened in the moment should be let go like water rolling off a duck's back. To me it's a fancy way of saying don't worry about it, just let it go.

Ducks are water birds. Their feathers are oily to keep them dry and warm. Water rolls easily and quickly off a duck's back rather than soaking into the feathers. So this expression means something like 'rolls off quickly and doesn't sink in.'

Its a funny British term that is very common there. Water off a duck's back means something that is easy, that doesn't make much of an impact. I think I have also heard "Water of a goose's back" too, which i presume means the same thing.
