Each year, the day after Halloween marks a special time for the world male population: the beginning of Movember. This celebration of facial hair lasts all month, giving gentlemen 30 days to sport their sweetest ’staches in support of men’s health issues. This year, the Silverton Casino Lodge joins the unconventional observance by hosting its inaugural “Mustachio Bashio.”

Patrons can partake in beer pong and live-band karaoke, listen to live mariachi music and enjoy dollar brews all night long. Celebrity judges will eye every upper lip to determine who goes home with the “Best ’Stache” title and an iPhone or iPad. Showing up both hairy and hungry is recommended, as a mashed-potato-eating contest is also planned for the furry fete.

Buy limited-edition “Mustachio Bashio” T-shirts while you’re there—all proceeds benefit the Juvenile Diabetes Research Foundation. Plus, they’ll remind your friends of the hilariously hairy party they missed.
