I’ve always been a fan of the ‘Hubba Hubba’ phrase, but I never knew where it came from. A quick Google search led me to the Smithosian, which breaks down the history of ‘Hubba Hubba’:
Like many expressions, the origin of “hubba hubba” is debated. Neatorama explains four of the most common theories, many of them beginning with the military. The first says that it came from the Chinese “ni hao pu hao,” and was picked up by Army Air Corps members while they were training with Chinese pilots in Florida during World War II. This version of history claims that the phrase spread through Bob Hope, the host of a weekly radio show broadcast from military bases. The problem with this theory that “hao pu hao” was completely mistranslated. It actually means “are you well,” but was mistranslated to “it is good under heaven when boy meets girl.”
The second military theory stays in the military but loses the Chinese. This one says the word “hubbub” was taken up by a military leader, who forced his troops to shout the words. The third military history says is that it’s a shortened and mutated version of the “hup hup hup” used by drill sergeants.
