We love publications that originate from being annoyed at everyone else. And in 1993, Debbie Stoller, Laurie Henzel, and Marcelle Karp were annoyed enough to create BUST, an alternative-feminist mag for young urban women in the know that goes beyond big boobs and big hair. A decade and a half later, BUST is still as pert as ever, celebrating its 15th anniversary with—what else?—a huge ass-kicking party in a circus tent! Funny lady Amy Sedaris—whom you might have spotted selling her yummy cupcakes at the glossy’s famous Holiday Craftaculars—will emcee tonight’s festivities, which include a hot lineup of bitchy entertainers like Murray Hill, Morningwood, Le Tigre’s JD Samson, the World Famous *BOB*, and the Pontani Sisters. Be sure to get there early: The first 500 people get goodie bags, and there’s free cupcakes and BUST magazine subscriptions for all. At 8:00pm, South Street Seaport, Pier 17, 207 Front St., 212-732-7678, $25
