《Bad Boy》Red Velvet英文版歌詞如下：
Verse 1：
Hey boy, what you doin' with a girl like me?
I'm all about the bad boys, not a little boy's game
Too many times, I've played them too many times
This little boy is too easy to play with
Chorus：
Bad boy, got me goin' crazy
With every single touch, it's all in my mind
Bad boy, I can't fight it anymore
The more he makes me scream, the deeper I'm feeling more
Verse 2：
Too many promises broken, so many games to play
But I'm not looking for a boyfriend, just a bad boy to stay
Too many boys try to impress me, but they don't get the memo
This one's different, he knows what he's doing, and I like it
Chorus：
Bridge：
And I know what I want, and I know what to do
To get what I need, it's not a mystery to me
I'm feeling it now, I'm feeling it real
So let's get it on, like we both know what we feel
Chorus：
Outro：
And I know you got a bad boy in you, just come out and play with me now
Come on, bad boys never say die, we can do this all night long.
