Movember ("moustache" and "November") is an annual, month-long event involving the growing of moustaches during the month of November to raise awareness of prostate cancer, testicular cancer, mental health and other male health issues and related charities.
The Movember Foundation runs the Movember charity event, housed here.
The goal of Movember is to "change the face of men's health."
By encouraging men (otherwise known as "Mo Bros") to get involved, Movember aims to increase early cancer detection, diagnosis and effective treatments, and ultimately reduce the number of preventable deaths. Besides getting an annual check-up, the Movember Foundation encourages men to be aware of any family history of cancer, and to adopt a healthier lifestyle.
So put those razors away for 30 days, chaps:
