The act of simultaneously of giving a blowjob to one person while taking a shit on someone else, while being shot up with heroin. Can be done with 3 people, but better with 4.

Dude, did you see those those 4 homeless guys doing the San Francisco Sourdough on the corner back there?

This is when a man and a woman, after enjoying some Rice-A-Roni—the original San Francisco treat—engage in a "69". The man proceeds to puke into the woman's vaginal orifice, and since she is from S.F., she is probably pretty hairy. Thus, the rejected Rice-A-Roni and the hair pie create a special sort of soufflé a third party (who has been watching or filming the 69) can then enjoy for her or his own pleasure.
