Movember: Get your mustache on and raise money for prostate cancer
But there are actual rules for the event, set forth by the nonprofit group.
First of all, the man must start the month of November clean-shaven. Secondly, throughout the month the 'stache must be kept nicely shaped. No touching of the side burns to the 'stache (beard), no joining the mustache to chin hair (goatee).
The goal is raise money and awareness of men's health, specifically prostate cancer and other cancers that affect men. The money each man raises is donated to programs run directly by the Movember group, plus the Prostate Cancer Foundation and LiveStrong.
The month was kicked off with the fifth annual "Stache Bash," held by the American Mustache Institute in Chicago.
