To overtake a vehicle on the wrong side. Dangerous, and illegal in many countries, especially Germany where Autobahn (motorway/freeway) laws are extremely strict. Favourite activity of audi man, usually at dangerous speed. Audi man will also cut you up afterwards.
EG, in the UK where one drives on the left and overtakes on the right, passing on the left is undertaking.
