San Luis Rio Colorado 

The place behind the gates of Hell, although the temperature is hotter than hell itself. Also a renowned shantytown with entitled motherfuckers who have no future. The only options are to stay and die or to move away and live to the extent of what is the real world.

Maricon: Ayy wei! Vamonos a chingar a San Luis Rio Colorado!
Mariela: Estas pendejo?? Ese lugar es un agujero de mierda, vete a la fregada, cabrón!

San Francisco Backfire

The act of trying to fart while a penis is going into your butthole, and when put in with enough velocity the gas bubble makes its way up and you end up burping.

Greg: Man I shoved it in so quick last night right before he farted that it went up and she had the old San Francisco backfire.

San Francisco Sparkling Disco 

The act of inserting an entire disco ball plugged into a wall into your partner's anus. To complete this sexually enticing piss, the inserter must then urinate all over the disco ball to create an effect that shimmers and shines.

Yeah, I gave that four year old one hell of a San Francisco Sparkling Disco yesterday. That'll teach her not to where that sexy looking skirt!

San Franciscan Kiss 

The act of two males masturbating with one another. Whilst doing this, one male close to orgasm will place the tip of his urethra with the other male's urethra and ejaculate inside.

Note to self: Never ask for a San Franciscan Kiss in San Francisco. Hell, never ask for one.
