A polite wave given by polite drivers when doing impolite things on the road (like in Washington State), such as pulling out of parking lots giving the driver going that direction just enough time to not total your car.
I really wanted to catch the light, so I floored it out of the parking lot. The guy I pulled in front of nearly had a heart-attack, so I stuck my hand out the window and gave him a good ol' washington wave to smooth things over.
