Once again, Bootie Mashup hosts the biggest Santacon After-Party in San Francisco, as a bunch of drunks in cheap Santa suits invade the party! Anyone dressed in a Santa suit or holiday-themed costume gets in for FREE before 11 PM (but only if they're fully-dressed and not TOO wasted!)

Launched in San Francisco in 2003, Bootie Mashup throws the biggest and best all-mashup dance parties in the world, mixing and matching pop songs both past and present. With its theme parties and clever mashup formula, Bootie Mashup has been an unstoppable juggernaut for nearly 15 years, winning numerous nightlife awards in multiple cities.
