San Francisco Kiss 

The most intimate of kisses; The San Francisco Kiss is when two people rub their buttholes together passionately as if simulating kissing. Not to be mistaken with the San Francisco French Kiss.

Look at those two men over there locked in a passionate San Francisco kiss; What a time to be alive.

A noticeable dent in a car fender, bumper, or door acquired while parked, left by an anonymous San Francisco driver who drives away without leaving any contact note or insurance info.

Damn it! Some a*hole gave my car a San Francisco kiss on the right front fender while I was parked in the Stockton street garage!!!

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.
