Verb - a suicide-attack used against an opposing player. From an Online
Multiplayer game called Netrek, Circa 1990+.
Roots of the verb began when a player who was playing for the origin team (O), with player designator 'g', used the tactic to sucessfully defend an area of the Netrek universe. (All players had a 1 character representation on the graphical screen. This
particular person's Designation happened to be "Og" at the time).
Enemy ships would take damage not only from your weapons, but also from the subsequent explosion of your ship.
Ogging, or "to ogg", is now considered to be a standard
online gaming tactic; and has been used for over a decade in Netrek.
