This is the prelude to "no-shave November." It is where shaving becomes optional due to a variety of factors, including the beginning of the MLB playoffs, your favorite NFL team being 3-1, plain old laziness, or the fact that one just needs some practice not shaving. It can also relate in northern tier states to the beginning of deer bow hunting.
Dude, you didn't shave today. Are you prepping for "No-Shave November?" "Yep, but it has a name. It's called Optional October."
