What is いやほい from the Kyary Pamyu Pamyu song 原宿いやほい HARAJUKU IYAHOI?


What does いやほい mean in this context? Or is it nonsense or onomatopeia? I'm not
finding a conclusive result in the dictionary.

Results I get are, for instance:

いや which could be disagreeable, increasingly, no, head house, birthplace,
originator

ほい which could be linen kariginu, supplement, heave-ho, yes, one's real intent

So... "no-yes"...? "linen kariginu originator"...? ...?




Most native speakers haven't heard いやほい before this song. When [an announcer
asked the lyricist about this word on
Nov/11/2015](https://twitter.com/search?q=%22%E3%81%9D%E3%82%8C%E3%81%9E%E3%82%8C%E3%81%AE%E3%81%84%E3%82%84%E3%81%BB%E3%81%84%22&src=typd),
he said something along the lines of "The meaning is not known and each person
has their own way of interpreting it". So it's basically his made-up word
which just sounded nice to him.

Still, I feel this is meant to sound like a symbolic 掛け声, something like "Yo
Ho" (of pirates) or "Heigh-Ho" (of dwarfs in Snow White). Some people seem to
believe this had been actually used among young people around Harajuku, but I
could not find a definitive evidence for that.
