Tiki refers to large wood and stone carvings of humanoid forms in Central Eastern Polynesian cultures of the Pacific Ocean. There are dozens of languages found in these islands which include, among others, New Zealand, Hawaii, Easter Island, Tahiti, and the Maori Islands. In the Māori language, the word 'tiki' was the name given to large wooden carvings in roughly human shape, although this is a somewhat archaic usage. The carvings often serve to mark the boundaries of sacred or significant sites.
According to the Maori Dictionary, wharepaku (also where paku or heketua) is the noun for toilet, lavatory, convenience, latrine, loo, bog. The "Wh" is sounded almost like an "F" and the R is pronounced rolling.
I tried to see if there were any unique designs for the Polynesian toilets, but they were disappointingly exactly like the American ones. Oh well, I like mine better.
