San Francisco 

The only city in America where weed is legal, but plastic bags aren't.

San Francisco is an awesome place to live.

San Francisco Christmas tree 

A four-person minimum gymnastic homosexual feat of strength, endurance, and simultaneous load blowing and collapse. A vertical structure of two human centipedes zipped together at the penii (see docking) that come together when the top two participants kiss to form the pinnacle of the tree.

Eric blew out his ACL because he thought he was strong enough to be the base of a San Francisco Christmas tree.

san francisco yes 

Always super-enthusiastically agreeing to plans and always, always flaking.

"Hey John, do you want to come to my daughter's wedding?"
"Yes, absolutely! I've been waiting for you to ask!"
***
Day of wedding, via text: "I can't make it, my dog is sick with the measles :-( Next time though!"
That's a San Francisco Yes.

san francisco left 

While driving, the act of passing the street you wish to turn left on, followed by 3 rights.

To make a San Francisco left on 19th Ave at Geary, make a right on 20th, a right on Clement, and then a right on 19th.

San Francisco 

Cold and foggy, contrary to the typical stereotypes of California.

"Where you going?"
"San Francisco"
"Oh, then don't bother packing those shorts."

Some Francisco 

any city or town in the world resembling San Francsico /California in terms of architecture, culture and whatnot

Bostonians may not share the same idea of Boston/Massachusetts being the Some Francisco of the Eastern United States but hey, it is to me!
