You look so real
你的形象如此逼真
But this ain't the type of dream
但這並非一場美夢
That I'm tryna keep

I'm gonna wake up
我將會醒來

Bad idea, bad idea
壞主意，壞主意
Don't say I didn't warn ya

Bad idea, bad idea
壞主意，壞主意
What if I just took a risk
如果我冒個險會怎么樣呢
I know that you want it, I'm thinking it too

It's a bad idea, yeah

Don't even think about it, girl, I won't take it
不要去想它，女孩，我不會接受它
Don't act like you care about me, I don't need your help

I'm gonna take my chances and I won't look back

"Bad Idea"是一首充滿挑逗和誘惑的歌曲，表達了女性對潛在危險的吸引力的矛盾情感。歌詞中多次重複“壞主意”，既暗示著潛在的危險，又似乎在邀請對方去冒險。這首歌在格蘭黛的專輯中也備受好評。
