During World War II, some United States soldiers in the Pacific theater used the word “lollapalooza” as a shibboleth to verbally test people who were hiding and unidentified, on the premise that Japanese people often pronounce the letter L as R, and that the word is an American colloquialism that even a foreign person fairly well-versed in American English would probably mispronounce and/or be unfamiliar with.[6] In George Stimpson’s A Book about a Thousand Things, the author notes that, in the war, Japanese spies would often approach checkpoints posing as American or Filipino military personnel. A shibboleth such as “lollapalooza” would be used by the sentry, who, if the first two syllables come back as rorra, would “open fire without waiting to hear the remainder”.[7]
