Because they're macaws?

[Cadaverous Pallor]

After a recent Tiki Room visit, GD and I were mentioning the lyrics and realized there was one part we never quite understood. I just looked it up and found that I've been saying it wrong.

The boys in the back are kamikaze
Because of their claws?
No, because they're macaws
And our fine feathered friend is a jolly toucan
And two can sound better than one toucan can

Kamikaze? In the song the word is pronounced kaw-ma-cause, not ka-mi-ka-zi. I thought the line went "the boys in the back are called macaws".

So what does it mean? Are macaws naturally violent? Was the mispronunciation an accepted Americanization of the term back then?

It seems there are always more mysteries to uncover in the enchanted tiki room.
