Faceroll

Faceroll is a computer slang term used mainly in MMORPGs. It refers to an ability or character class that's so easy to play that someone could bind all their keyboard keys to one action and roll their face across the keyboard. More plainly, the ability or class is so overpowered that there's no need for skill, timing, or diversity of gameplay.
