Fight-Finishing Fist Frame

This refers to a frame in a comic book or cartoon where the hero has knocked out the villain and the viewer sees only one still frame of the final punch being landed on the bad guy. There usually is no dialogue, just the single action, occasionally there's a snappy one-liner. A brightly coloured background is often used resembling a pseudo-anime style. This is used in every episode of Batman: the Brave and the Bold cartoon series.
