Due to recent PC evolutionary action, certain words have been found to be offensive in case, plurality, etc. To assist in not offending the gramatically challenged, newer words will, where possible, be their own plurals. So, like sheep, dudu and dudi may be singular or plural, or perhaps both simultaneously, and, in rare cases, neither.
Further, to avoid the conflict with the old term dude, the official PC term for non-age-specific homonoids of the masculine persuasion (gender challenged?) is now dudo.
Dudo and duda will continue to be singularity-challenged by the addition of an 's', forming dudos and dudas, in the interest of harmony with our Latino friends around the world.
Usage of the term dude is deprecated, except in California and its derived cultures, where it is essenially a meaningless syllable uttered upon random events.
