Mud wrestling is so over. It's like Dynasty or that mechanical-bull thing that John Travolta made famous about 50 years ago in Oklahoma or Kansas or wherever that movie was. Here in sexy San Francisco -- in the enlightened 21st century -- we have lube wrestling, namely Go Deep: Let's Wrestle. It's acted out by burlesque performers who shout "Glycerin sensitivity be damned!" before hopping into, well, it's not really a ring but more like an inflatable playpen. The monthly happening is pro-am, so anyone can sign up. Previous pros include performers from Thrillpeddlers, Belladonna Beauties, and Ultimate Surrender. DJ Ruby White spins tunes. Prizes go to the victors. The menu includes something called "family meal" (which sounds pretty dark to us). It's put on by Red Hots Burlesque, who remind us, "No one can resist hot babes covered in glistening sex slick writhing and wriggling in attempts at pinning each other." Make a reservation and get a ringside seat -- only, wear something you don't mind being wet and sticky for a few hours.
