A politically incorrect term for chaos. The phrase supposedly originated in the early 1900s. A ship with British officers and a Chinese crew practiced an engine room fire drill. The bucket brigade drew water from the ship's starboard side, carried it to the engine room, and simulated throwing it on the “fire.” Another crew carried the buckets to the main deck and threw the water over the port side. But when orders became confused in translation, the bucket brigade started to draw the water from the starboard side, run over to the port side, and then throw the water overboard, bypassing the engine room completely. A 1960s stunt was for a carload of teenagers of college students to stop at a red light, whereupon at the command “Chinese fire drill,” driver and passengers got out, ran around the car, and returned to their original seats. The same idea is sometimes heard as the equally politically incorrect “Chinese square dance.”

Military inspection for venereal diseases. Beginning with World War II, the military made visual determinations with regard to sexually transmitted diseases (primarily gonorrhea) through what was called a short arms inspection (or drill). Held early in the morning, men dressed in only their boots, helmet liners, and overcoat were summoned out of their barracks or bunks and ordered to line up. When indicated by the medical officer, each man opened his coat to bare his penis, which he then “milked” in a stripping motion to show whether there was any infectious discharge. The term distinguished between a man's governmentissued firearm and his own “short arm.” The inspection practice ended after the Vietnam conflict.
