mousekatard

One who is new to computers and has limited or no control whatsoever over the mouse, frequently becoming frustrated by their own lack of coordination and inability to master eye-hand coordination at a level a two-year-old would have little difficulty achieving.

It's too bad about Betty. She's such a mousekatard she accidentally dragged her entire hard drive to the trash and lost her system, then got the cord tangled around her neck and suffocated.
