jitter
- n small rapid variations in a waveform resulting from fluctuations in the voltage supply or mechanical vibrations or other sources
- n a small irregular movement
- As soon as the insane stumble and jitter onstage with their dreadfully absent eyes, their bodily tics, their slavering mouths, their heads lolling like half-decapitated flowers .
- A wide-eyed, sportily clad lass with a dink perched on loosely brushed locks, Sally steps around in gillies and low socks, will jitter like any Benny Goodman votary in the .
- When you stand far away, every hand jitter affects the framing and focus of the shot.
