Papakangahorohoro doesn't even look or sound hard. If you want hard, try wrapping your head around figuring out how to pronounce Welsh - Who are the real British people, and not those savage Germans calling themselves "English" -

For example, imagine your touring the village of Llanhyfryddawelllehynafolybarcudprindanfygythiadtrienusyrhafnauole and decided you wanted to catch a train to Liverpool but on your way there you accidentally take the wrong train and end up in Fairbourne at Gorsafawddachaidraigodanheddogleddollonpenrhynareurdraethceredigion rail station. Makes for a great photo opportunity at least.
