California Good-Bye 

When you give a male/female that is leaving California for another State/Country the best pleasure before they leave.

I gave Christine a California Good-Bye before she left for Chicago.

Southern California Goodbye 

A customary way that friends in Southern California leave events together: two or more people walk to one person's car, and that person drives everyone back to their cars.

The Southern California Goodbye is a response to lack of public transit in a region which is now literally over 14% parking lot (not counting freeways, which in Southern California are also effectively parking lots).

SoCal person A: Where did you park?
SoCal person B: This side of the parking lot. You?
SoCal person A: That side of the parking lot.
SoCal person B: That's hella far. Southern California Goodbye?
SoCal person A: Thanks fam.

California goodbye 

The way a Californian says goodbye to a person who they find sexually attractive by giving them the best sex they’ve ever experienced and leaving them wanting you/them to stay instead of going home.

Californian: thanks for showing me texas, let me show you a California goodbye.
Person: what’s that?

California Irish Goodbye 

Abandoning your friends at a party/bar/dinner without saying a single word to any of them, usually resulting from being very intoxicated. California Irish Goodbye's are risky for the DUI exposure. Also deserting your buds 10-20 miles away from their residence deserves an ass kicking.

Where's John at, I haven't seen him for over an hour.

I dunno, someone mentioned he did a sneaky California Irish goodbye a while ago.
