As described by the official Movember website:
During November each year, Movember is responsible for the sprouting of moustaches on thousands of men’s faces, in the US and around the world. With their Mo’s, these men raise vital funds and awareness for men’s health, specifically prostate cancer and other cancers that affect men....Considering the subject matter, I thought cookies-on-a-stick would be the perfect way to package these "hairy" morsels of butter and sugar.
Mo Bros effectively become walking, talking billboards for the 30 days of November. Through their actions and words they raise awareness by prompting private and public conversation around the often ignored issue of men’s health.
