I was talking with a lady about the recent downpours and how one road was so flooded that I had to drive on the opposite side. I was telling her that the water formed a lake on one side of the road and she said, "Mamaigo' i hanom." The water was sleeping. This idiomatic expression is used for any stagnant or unmoving fluids. It is used also, for example, for thickened or coagulated blood. I haga' ni mamaigo'.
