1.
The "hat" of snow left on the roof of a car when the owner has cleaned the windows but not the rest of the vehicle. Usually encountered when the driver is too short or too lazy to access the roof.
On the highway, I swerved to avoid an airborne carcake which had just blown off the car in front of me.
