说实在的，原曲歌词没改基本上就很符合现状了....
Hot 'N' Cold - Katy Perry
MV：https://www.youtube.com/watch?v=kTHNpusq654
(强烈先看一下才会知道为啥我想选这首，
因为明天很想看到这场景出现在立法院)
原歌词：

You change your issues 你改变你的诉求
Like a girl changes clothes 就像女孩换衣服
Yeah you, PMS 对阿 你根本就有经前症侯群(注)
Like a bi*ch 就像个○货
I would know 我早该知道了
And you always think 你总是觉得
Always speak correctivelly 你说的永远是对的
I should know 我早该知道
That you're no good for me 你根本不适合我
Cause you're hot then you're cold 你一下热情 一下冷淡
You're yes then you're no 你一下说好 一下说不好
You're in then you're out 你一下这样一下那样
You're up then you're down 你一下开心 一下不开心
You're wrong when it's right 你错了硬要说成对的
It's black and it's white 事情是黑的你却说白的
We fight, we break up 我们吵架然后决裂
We apologize, we make up 然后我们道歉又合好
You don't really want to stay, no 其实你一点都不想留(立法院)，喔你不想
But you don't really want to go-o 但你又不想真的离开(立法院)
you're hot then you're cold 你一下热情 一下冷淡
You're yes then you're no 你一下说好 一下说不好
You're in then you're out 你一下这样一下那样
You're up then you're down 你一下开心 一下不开心
(注)PMS，经前症候群：
大多数育龄女性于月经前的一至两周会有一些经前不适症状，
容易出现生气或易怒，情绪低落，烦躁不安等情绪状况
