Metronomic Man-Mashing

One way for a character to deliver a severe beatdown on an opponent is to pick said opponent up (often by the feet) and slam him left-right-left-right overhead into the ground. It's generally an indication that either the character doing the slamming is very strong, or very angry. This can be played for even greater effect if the character doing the slamming is either very small or, in normal circumstances, shouldn't have that kind of strength at all.
