文法:"But girl, don't they warn

My dear friends,
The enclosed song is cool, but do you know what grammar it is for the sentence
"But girl, don't they warn ya". 這是什麼倒裝句嗎??

Thanks a lot for your help ^^

搭上飛向西部的747
Didn't think before deciding what to do

All that talk of opportunities, TV breaks and movies
所有的夢寐以求的機會就要實現 我要躍上大螢幕
Rang true, sure rang true.

Seems it never rain in Southern California
聽說 南加州從來不下雨
Seems I've often heard that kind of talk before
我以前常常聽見人們這麼說
It never rains in California

But girl, don't they warn ya

It pours man it pours.
