When involved in a politically-tense situation and all progress has halted in discussions, it is the practice of applying percussive-logic to your opponent in the form of a beat-down.
"Justin was ignorantly speaking about 'homos' again last night at the bar. But my gay cousin was with us and got really upset. So I stuck up for my cousin and argued with Justin until he threw a beer at me. At that point I switched to pugilistic-diplomacy and prevailed in the argument."
