Well it would not literally own people. In the world of video games or just plain old fucking people up it sure does own. Just like it is me owning someone when I hit them with a headshot in a videogame or in real life. They got owned. When I die I will get owned by something, lets say I get owned by heart failure. I make that type of joke all the time. "That guy just got owned by that car while riding on his bike" would be another good example. Usually when you own something it isn't good for the thing being owned.
It is horrible that stuff happens actually. Yet another way of dealing death, humanity never ceases to amaze.
