Spit balls of fire! Tonight, the third annual Sister Spit’s Ramblin’ Roadshow comes to Washington to stun, charm, and kick some spoken-word butt in a town that needs it bad. Sister Spit was formed in San Francisco several years ago by poets Sini Anderson and Michelle Tea as an all-girl open-mike night in response to the city’s boy-dominated spoken-word scene. Rejected by a well-known women’s music festival, these self-proclaimed loud and raunchy women of words decided to take their show on the road in 1997, old-school vaudeville style. Besides a lineup of outspoken dyke-femme-neither-both performance artists and writers, presided over by MCs Anderson and Tea, the Roadshow promises leather, multicolored pigtails, and performer-encouraged heckling. Check out the word-slinging for yourself at 8 p.m. at Metro Cafe, 1522 14th St. NW. $10. (202) 775-8218. (Irina Slutsky)
