The act of changing a game to make it another, or add features previously unavailable, old, or previously nonexistant. It is commonly done in PC games.

Despite popular belief, modding IS NOT simply changing attacks of characters such as in RTS games or making them available to create, also in RTS games.

REAL modding is changing models and/or making new models.
I was modding Battle For Middle Earth 2 by changing Sauron's attack when some one told me real modding was making new models to add into the game.

Often this term stands for modification; in reference to vaping pens, a mod is simply a vaping pen (type of electronic cigarette) with a bigger battery, and more functionality to give a device which holds a charge longer, produces more flavor, more "throat hit", and usually offers other functions such as variable voltage, variable resistance, and recently temperature control. Mods are continually being improved, e.g. with computerized electronics which can be upgraded via bluetooth connection.
Have you seen the newest mod by Inokin? It has overcharge protection, a puff counter, temperature control, and allows for sub-ohm vaping for more flavor.
