Pink snowmen riding horses draped in glass ornaments. Mrs. Claus holding a pie adorned with candy canes. A sleigh driven by Jesus. A towering tree covered in cookies keeping watch over a children’s choir. These are but a few of the ugly Christmas sweaters in the world, and if you’re unlucky, you might spot one at the seventh annual Ugly Christmas Sweater Party. Other than barf-inducing garb, the night features the “teenage pregnancy music” of Frankie Boots; 8th Grader, from the band Music for Animals; and Eli, who many know as the sex-obsessed rapper Smoove-E. It gets steamy on Friday, Dec. 23, at the Hopmonk Tavern. 230 Petaluma Ave., Sebastopol. 8:30pm. $10. 707.829.7300.
