A term derived from the graduate working group of a professor at a research-one university in Southern California. A shower sentence refers to the "take-home" message of a text. A good shower sentence is characterized by one's ability to easily recall the main point of an article or other piece of literature--so good that even when waking up and barely conscious in the shower, one is able to remember the main point clearly.
