No Shave November is an annual tradition where guys and some girls participate in not shaving their beards and/or legs (or both!) in the month of November. Some call it silly, while others call it a liberating experience to not have to worry about shaving for a whole month. With winter around the corner, some think it's a perfect time to grow out their hair so it will keep them warm during the winter. No Shave November has also become widely popular among different causes/charitable organizations so growing out your 'stache for a good cause makes it all the more enjoyable.
If you just search for "No Shave November" you'll find a few websites in place that are already gearing up for a month long of hairy folks.
If you are participating in No Shave November, may the no shaving force be with you!!! LOL
