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."
