mouse-finger 

In computer video game terminology the mouse-finger is the dominant, or preferred, finger the video game player uses to wield their most valuable implement of destruction, i.e. the computer mouse. Without one's mouse-finger one is completely helpless.

Joe: *Crack* Damn!
Mike: Hey Joe, why the expletive?
Joe: I just broke my mouse-finger. I won't be able to finish the Unreal Tournament.
Joe: Your passing will be remembered in our myths and legends for years to come. Rest in peace.
