ogg
     
         /og/ ({CMU}) 1. In the multi-player space combat game
        {Netrek}, to execute kamikaze attacks against enemy ships
        which are carrying armies or occupying strategic positions.
        Named during a game in which one of the players repeatedly
        used the tactic while playing Orion ship G, showing up in the
        player list as "Og".  This trick has been roundly denounced by
        those who would return to the good old days when the tactic of
        dogfighting was dominant, but as Sun Tzu wrote, "What is of
        supreme importance in war is to attack the enemy's strategy."
        However, the traditional answer to the newbie question "What
        does ogg mean?" is just "Pick up some armies and I'll show
        you."
     
        2. In other games, to forcefully attack an opponent with the
        expectation that the resources expended will be renewed faster
        than the opponent will be able to regain his previous
        advantage.  Taken more seriously as a tactic since it has
        gained a simple name.
     
        3. To do anything forcefully, possibly without consideration
        of the drain on future resources.  "I guess I'd better go ogg
        the problem set that's due tomorrow."  "Whoops!  I looked down
        at the map for a sec and almost ogged that oncoming car."
