Movember (the month formally known as November) is a moustache growing charity event held during November each year.
At the start of Movember guys register with a clean shaven face. The Movember participants known as Mo Bros then have the remainder of the month to grow and groom their moustache and along the way raise as much money and awareness about male health issues, in particular prostate cancer as possible.
You can register or find out more at The Republic of Movember. Link -via the Presurfer
