WASD refers to the keys W, A, S and D used in an inverted-T configuration as cursor keys, predominantly in computer games such as first-person shooters (FPS).
Although there are older games that used it, the use of WASD became popular mainly with the pro gamer Dennis "Thresh" Fong back in the late '90s when playing Quake (1996). The first FPS game to offer the WASD setup as default is believed to have been Half Life (1998).
These days, there is a category of one-handed keyboards for gaming ("gaming key pads") that have only keys from the left hand side of the keyboard, centred around the WASD keys, sometimes with more options such as built-in joystick.

The specific term is also nationality dependent; for example, in the French AZERTY layout, the same keys are labelled ZQSD.
