DJ Purple's Karaoke Dance Party happens every Thursday night at Jack's Club. Forget the sloppy drunks half-assing their way through Aerosmith and Beyoncé songs. DJ Purple's Karaoke Dance Party is all about Iron Maiden, Snoop Dogg, Led Zeppelin, and Riskay. No slow songs allowed. An actual experienced DJ, Hays keeps the beats running smooth, fading and blending as each person stumbles onstage, and even stepping in for saxophone solos and backup vocals when a song calls for it. And sometimes even when it doesn't.
Thursdays, 9 p.m., free. Jack's Club, 2545 24th St., SF. (415) 641-5371, www.djpurple.com
BEST FLANNEL REVIVAL
In this age of continual retro, it comes as a surprise that listening to mainstream '90s alternative rock can give you, under the right inebriated circumstances, the kind of pleasure not experienced since heroin went out of vogue. Debaser at the Knockout has become one of the best monthly parties in San Francisco, largely because it gives '80s babies, who were stuck playing Oregon Trail in computer class while Courtney Love and Kat Bjelland were rocking it out in Portland, the chance to live out their Nirvana-era dreams. Debaser promoter Jamie Jams is the only DJ in San Francisco who will spin the Cranberries after a Pavement song, and his inspired mixology is empirically proven to induce moshing en masse until last call, an enticingly dangerous sport now that lead-footed Doc Martens are back in style. Sporting flannel gets you comped, so for those still hung up over Jordan Catalano and the way he leans, Debaser is rife with contemporary, albeit less angsty, equivalents.
First Saturdays, 9 p.m., Knockout, 3223 Mission, SF. (415) 550-6994, www.myspace.com/debaser90s
BEST CRANIUM MONOPOLY SCRABBLE RISK
The shaky economy's probably put your $60 concert plans on hold and relegated those high-rolling VIP nights to the back burner. So it's a great time to return to the simpler forms of social interaction, such as shaking some dice and screaming, "Yahtzee, bitches!" or guffawing maniacally every time some poor fool attempts to pass your two hotels on Boardwalk. Fortunately, game night at On the Corner café on Divisadero fills your staid Wednesday evenings with enough card-shuffling, Pop-o-matic popping, I-want-to-be-the-thimble classics to sink your battleship blues. Plus, there's coffee and beer. Working in collusion with the colossal collection of neighboring Gamescape, On the Corner provides a plethora of gaming options to fit its large tables and vibrant atmosphere. Stratego, Scattergories, and other trivial pursuits are all available, and the 7 p.m.-<\d>to-<\d>closing happy hour includes $2.50 draft beers and sangria specials. The tables fill up quickly, though arrive early so you won't be sorry.
Wednesdays, 710 p.m., free. 359 Divisadero, SF. (415) 522-1101, www.sfcorner.com
BEST PARTY OF ONE
Perfect moments are never the ones you work hard to create. Too much effort kills the magic. Instead, the moments we treasure are those that steal up on us, slipping past our defenses to reveal, for just an instant, the sublime wonder of the universe. This is precisely what happens during one's first encounter with the Lexington Street disco ball, innocuously spinning its multifaceted heart out on a quiet neighborly block in the heart of the Mission District.
