Get the san martin rodriguezmug. San Diego 69 is when 2 to 4 homeless crackheads eat each other up until one gets off. Then, when the first one reaches climax they start tongue punching each other's fart box. That's when all 2 to 4 crackheads will come together to conjoin like a big ass power ranger on the best crack ever made in San Diego.

Get the San Diego 69mug. Male homosexual sex act. A cart or dolly-like object is placed on the ground. Man (naked) kneels down on dolly. Second man mounts first from behind, placing penis within the first man's anus. By repeatedly thrusting into the anus, the second man propels the cart forward, as if it were a trolley. It is possible, either using their weight or with the first man's hands, to guide the trolley.
(Optional) For the full experience, second man should have some sort of whistle, so as to act like a train conductor.
