The word lollapalooza seems to originate from the islands of the South Pacific. It became popularized (to a very minor extent) during World War II. It seems that the Allies used 'lollapalooza' as a code or password to differentiate between Chinese and Japanese forces. The Chinese were able to properely pronouce the 'L' sounds, the Japanese could not.
This information imparted unto me by the Japanese Teacher of English, Watanabe-sensei.
