Just hold down the trigger and that AFK'er will be dead in no time!

When firing a weapon in Counter-Strike 1.6, your crosshair will expand to represent the loss of control and recoil. The longer you continue firing, the further it expands until it reaches a maximum point of expansion. When you cease firing, your crosshair will shrink back to its normal size, allowing you to easily line up another target in your crosshair and begin firing again. This is also true to Counter-Strike: Source, but with a slight difference. In CS: Source, your crosshair does not smoothly transition back to its original size, instead it seems to shrink back in phases, one size at a time. This process takes a couple seconds longer than CS 1.6, making recoil harder to control.
