I sometimes use the nonsensical word hullaballa for bogus input or output in testing, like username, passwords, log messages etc.
It does not seem to be the first magazine with this name; there is an article from a 1931(!) issue of Time Magazine stating:
When the incredible magazine which is now Ballyhoo was in preparation. Publisher George T. Delacorte Jr. wondered what to call it. He and Editor Norman Hume Anthony favored Hullabaloo for a title but were afraid it might infringe on the rights of Cartoonist Peter Arno whose book of last year bore that name.
