When someone pays way too much attention looking at a visual effects shot in a film. Often happens when examining the grain of a composite element to make sure it matches the film stock. Someone who pixel-fucks pays more attention to things like grain than the overall effectiveness of the shot. This is often because they are small-minded bean-counters, and miss the point of a shot entirely.
