San Francisco Soufflé 

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.

Jane and I were going at it, and I left a San Francisco Soufflé in her snatch for Sara.

San Francisco shuffle 

The act of using the escalator handrail to mechanically wipe one's ass due to the toilet paper shortage of the Corona Virus

The mall bathroom was out of toilet paper so I pulled a San Francisco Shuffle in front of Macy's.
