According to WIKIPEDIA, Movember means:
Movember (a portmanteau of the word 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 and other male cancer initiatives.
So the guys go for growing moustaches...
Women go for...drum rolls...
Moustaches on our nails! ;-) Find here the tutorial on how to DIY!
Happy Movember y'all!
