Button Slapper

One who lacks even a smidgen of ability in any video game, and in a panic rage of desperate attempt, slaps the entire controller / keyboard in an effort to scramble a victory.

ie. "Tom, why is it that every time I kill you in Halo, I hear a fury of panic slaps right before you die?"

Tom: I'm so out of practice, I go into full button slapper mode as a last resort.
