We also have very descriptive words for the wet stuff, such as:
Monsoon, damp, cold, drenching, soaking, sopping, slick, precipitation, glistening, showers, droplets, drizzle, spitting.
Most of these come from our daily weather reports on the evening news.
And I am sure that you can come up with some zingers of your own. Be creative, unless of course you are waterlogged.
