That sounds like a good title for a book or something. Like the sequel to "Catcher in the Rye". Seriously though this is about video games.
Suicide, as used by gamers, is a different word to suicide as used by non-gamers. When a non-gamer uses it, it’s usually talking about intentionally getting one-self killed... Or something. I can’t really tell because I’m a gamer and use suicide in the awesome way:
Note that I used verbage 1 there. That’s not what I mean. In gaming, suicide means “to make decisions that will lead to your character's demise”. Does that sound similar to the original definition? It is, and that’s probably where the term got borrowed. To some extent, it still applies to getting yourself killed on purpose — for example, running up to a group of enemies and getting shot at until you die, is suicide. I doubt something like that would be considered suicide in the real world.
However, the term is used even more loosely, depending on the context. You can “suicide” in an FPS when you, say, mis-aim a grenade. You clearly did not intend for the grenade to bounce back at you and kill you, but it was clearly your own fault. More advanced players can “suicide” by being in an unfavourable position “Man I just committed suicide, was caught on the hill and wasn't crouching” 2. In an RTS, you can commit suicide by committing your troops down a path or to a location which you ought to know is going to lead to their deaths -- “Dang I walked right into suppression. My whole army suicided”.
What I like about this is that in a world where people ignore their responsibilities and fail to accept facts that they can see directly, the line of control and responsibility taken for your action in a game is so great that anything where your own actions lead to your demise can be identified as a decision on your part, and you take the blame accordingly.
1 For some strange reason the internet uses verbification instead of “verbage”, which I’m used to using for the same definition.
