I used to play GTA: San Andreas online, and in a roleplay server, yes I know, lame.
Anyhow, /me commands were needed to be used and they would show a message like so,
*John_Smith clutches his head.
So anyway, once my brother was driving along and he had a big carcrash with someone, and he wasn't bothered to roleplay it all, so he just said, /me dies. And then type /kill (which kills you), anyway, turns out that because he did that, it meant his character had actually died, and it was a 'CK', so he couldn't use his character anymore,
