When a young woman corners you in a mexican restaurant and demands that you grab her breasts. Alcohol is usually involved.
Dude, I was just chilling at Rigos and a girl gave me a California Handshake then offered me a beer.

When you are fucking a girl doggystyle who's vagina is extremely loose, you reach your hand inside from behind and jerk yourself off whilst fucking her.
"Did you hear I banged her? Yeah, gave myself a California Handshake while I hit it from behind"
