When you get hit by a mobile phone in the head from over 12 feet away. The mobile phone doesn't have to be made by Nokia, it could be made by any mobile phone company. To "Nokie" someone you must also cause some physical bruising to the head. Which is why it takes incredible skill to "Nokie" someone.
If you hit someone with a mobile phone from over 12 feet away you would shout: "YOU JUST GOT NOKIED!". Or if you were the person who got hit you would say: "I just got nokied!".
