Back of Movember: When Men Grow Mustaches For a Good Cause For dudes, November is not just the eleventh month of the year, it's Movember (as in "Mo" being Australian slang for mustache). Participating men start at the beginning of the month clean-shaven and grow in mustaches over the course of the next 30 days. While most of you said you don't love a man in a mustache, maybe you'll change your mind when you hear the whole Movember movement is for a good cause. The Movember Foundation is a nonprofit that helps raise funds and raise awareness of men's health issues, specifically cancer. Last year, over 255,000 people raised $40 million across the world.
