When you are playing a video game and you suddenly get attacked and it is totally unexpected. Similar to the events on 911.
2 friends where enjoying a game of Terrorist Hunt in Tom Clancy's Rainbow Six Vegas 2 and suddenly the event's of 911 were repeated. 8 terrorists flanked the 2 friends and they were dead in seconds. This is literally 911.
