The act of piling up multiple men (bottoms) on top of each other. Then the top roughly inserts his manhood into each participant starting from the flap jack on bottom and working his way up. The top proceeds to flopp out his load on the bottom, who is located on the top of the San Francisco Pancake. His semen then proceeds to trickle in a downward flow to the other members of the San Francisco Pancake. This should give the perception of a stacked pancake with syrup drizzling down. Like the Canadian Pancake but MORE GAY.
Andy asked me if I wanted to be in a San Francisco Pancake. I replied, "yes, so long as I got to be the flap jack."
