The sexual act of jizzing, shitting, and vomiting on an unsuspecting woman's (or man's?) chest (in no particular order), making a very disgusting pizza. Then for added entertainment, rub her jugs together to slice up the pie.
Man: I met this chick at the bar with a tramp stamp that said "Cali 'Za" and I had no idea what it meant.
Friend: Did you ask her about it?
Man: Yeah, then she took me back to her place and had me cum, shit and throw up on her chest, she called it a "California Pizza"
Friend: Why would you even do that?! shit.

The act of eating 10 pepperoni pizzas while your ass is simultaneously plugged up (to mimick the effects of constipation). Then shitting on a newspaper and making your partner read it.
Dude, I saved the newspaper from the day after 9/11 and decided to do a California Pizza Kitchen for my girl. I think she'll like it.
