Dishwater

I dumped the dishwater on the flowers so it wasn't wasted.

Tom put the dishes in the dishwater.

Tom is as dull as dishwater.

This coffee tastes like dishwater.

Change the dishwater if it becomes too dirty.

The dishwater drained away slowly.

This season's offerings are nothing but dishwater.
