splash (someone, something, or oneself) with (something)
To slosh or spatter some liquid onto someone, something, or oneself. The frying pan keeps splashing me with hot grease. I don't know why everyone thinks this painting is so brilliant. It looks like the artist just randomly splashed a canvas with paint! He splashed himself with cold water to help wake up.
