An in-game recording of a video game, pretty much exclusively PC games. They are often taken of competitive matches in games like Counter-Strike and Call of Duty.

Demos can only be played back within the game, however they can often be exported into actual video clips for use in frag videos (or "montages").

Though time-consuming, many games allow you to do all sorts of things with demos; search YouTube for demo recording tutorials to learn more.
