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.
Rice-a-roni? I don't think so... When a male proceeds to insert his penis into another male's rectum and engage in sexual intercourse. The man performing the act must then ejaculate(skeet skeet) within the other man's bowels, the receiver then drops his glazed fecies into a bowl and the thruster then continues by eating the freshly made San Fransico Treat.
"Did you hear those guys Richard and Huey have been counting how many San Fransico Treats that they have eaten during the past week? They're into the double digit figures!"
The act of two males masturbating with one another and ejaculating at the same exact time. The result is the ejaculated sperm colliding with one another.
This should not be confused with a "San Franciscan Kiss", which is similar, but one male ejaculates into the urethra of another man during or before the other male's orgasm.
"Man, did you seeJack & Terry's room?"
"Yeah. It looked like a pulled a San Franciscan Pileup on the place!"
