What is fragging?

It's a term used in the Vietnam War. It means to assassinate an unpopular officer in your own fighting unit. In games, it means to kill someone when they are able to re-spawn. The result of being fragged varies in different games. In many, you lose most of your items, except the ones that are completely essential. In others, your opponent gets your items or money. Usually, re-spawning results in the user being at full health without any of the objects that they've acquired, but some require that you recover the health you've lost.
