SFist Tonight

CLUB: GAY: Pre-cum stains abound if you hit up this pre-Folsom Street Fair bash, Kink-Wear Underwear Party, happening in the bowels of SoMa. Be sure to sport your kinkiest underwear: leather, cotton, Hanes, Paul Frank tighty-whities -- all panties are welcome!

10 p.m. // Powerblouse (1347 Folsom) // free

CLUB: JAZZ: The lights dim at this Mission venue when DJ Evan spins hand-picked jazz rarities and classics from the 1920s. Expect drink specials and a decadently-dressed crowd at Jazz Hands, which appens on the last Thursday of each month.

9: 30 p.m. // Makeout Room (3225 - 22nd Street) // free

FILM: Feeling a bit Felliniesque? Catch La Dolce Vita (1960), where Marcello Mastrantonio is "torn between the allure of Rome's elite social scene and the stifling domesticity offered by his girlfriend, all the while searching for a way to become a serious writer." (Fun fact: the word paparazzi was introduced in this film, taken from the name of Walter Santesso's character Paparazzo. So, there's that.)

7:30 p.m. // Castro Theatre (Castro & Market) // $9.50
