Having anal sex with a person to completion and then urinating in that person's anus.

Invented by David Cross on 1/28/16 in San Francisco during a comedy show at Davies Symphony Hall.
After anal sex, he wanted the feeling of a warm colonic rushing into his lower intestine, so I gave him a San Francisco Gold Rush.

Get the San Francisco Gold Rush mug.
Drug an old rich widows cougar drink at a club. Take her to a cheap hotel room, fuck her til she passes out, steal all of her jewelry and leave before she wakes up...
I pulled the good ole San Francisco Gold Rush again last night...
