CHINESE FIRE DRILL
A situation of chaos, confusion, or disorganization has been expressed as a Chinese fire drill since the mid-fifties . This is now considered offensive to the Chinese, and individuals of Chinese descent may take offense. The equivalent in Spanish is also politically incorrect, as it may be considered a slur for people of African origin: merienda de negros . So when a situation is confusing and chaotic, do not use Chinese fire drill or merienda de negros . Remember that forewarned is forearm!
