The Term "Fragging" and it's origin.

For those who play videogames, I am sure that you have heard the words "frag" or "fragged" before. If you haven't, consider this a quick history lesson.

The term in video gaming is as such: "Frag is a computer and video game term originating from the word fragging, a term indicating to kill an unpopular superior officer with a fragmentation grenade. A frag is roughly equivalent to "kill", with the typical main difference that the player being "fragged" can instantly respawn (play again) in most games, i.e. the "kill" is only temporary."

The origin of the term: "In the U.S. military, fragging refers to the act of attacking a superior officer in one's chain of command with the intent to kill that officer. The term originated during the Vietnam War and was most commonly used to mean the assassination of an unpopular officer of one's own fighting unit. Killing was effected by means of a fragmentation grenade,[1] hence the term.
The most common motive for choosing a fragmentation grenade or similar device is a perpetrator's desire to avoid identification and the associated consequences at either the individual level (e.g., punishment by one's superiors) or the collective level (e.g., dishonor brought to one's unit): when a grenade is thrown in the heat of battle, soldiers can claim that the grenade landed too close to the person they "accidentally" killed, that another member of the unit threw the grenade, or even that a member of the other side threw it. Unlike a firearm projectile, an exploded hand grenade cannot be readily traced to anyone, whether by using ballistics forensics or by any other means. The grenade itself is destroyed in the explosion, and the characteristics of the remaining shrapnel are not distinctive enough to permit tracing to a specific grenade or soldier."

So know you know what the term “fragging” means. I don't know why or how it got popularized in video games, or for that matter when grenades became "nades," but please understand that certain vets knows this word to mean something very different from its use today.
