I think in most of the US it is called a "California Stop" or "California Roll". Some of my relatives from Whittier, CA called it a "Hollywood Stop". The funniest I have heard is the "Come to a complete slow". The other one was "The bold life choice".
Of course being from somewhat rural Nebraska I have also heard it called a "Farmers Stop".
The funniest joke I recall related to this went something like this:
The new lawyer that had just passed the bar did a rolling stop. Then he sees the lights come on and pulls over to the curb. The policeman asks for his License and Registration, but when the policeman hands over the ticket, the lawyer says he did slow down and check for traffic and that he will only take the ticket if the policeman can show him the difference between a rolling stop and a complete stop. The policeman says, OK, then takes out his night-stick and starts bludgeoning the lawyer. After about 30 seconds the policeman asks the lawyer "Do you want me to stop or should I just slow down?".
