Synonymous with No Sex November. Men participate in this "manly month" to prove... something... no one's really figured out what yet. Unfortunately, participation in No Shave November also grants you full access to the synonymous month.
I'm not getting laid Billy, it's No Shave November, remember?

The act of shaving on October 31st then not shaving for the entire month of November. This includes all hair on the body. ALL HAIR! On December 1st each person in the agreement will swear whether or not they have shaved and provide at least 2 signatures from family members stating that the participant hasn't shaved all month. Whoever loses must pay for the other’s Chipotle meal. If no winner is declared then all participants will reward themselves with Thai iced teas; complete Asian cuisine lunch optional. It only becomes acceptable to shave again on December 1st.
-You ready for No Shave November?!
