Hey, no!
Alright, alright
Bad boy, bad boy
Alright, 1, 2, 5, uh

요즘 나 조금 패닉 상황 (ha)
솔직히 완전 홀릭인데 (hey)
머릿속 어떤 녀석 그 생각 하나뿐이야
One, one, one, one
One, one, one, one
One, one, one, one

Ah, ah, ah (alright, hey)
친구들 say 걔는 안돼 너무 나빠 네가 다쳐
Ah, ah, ah (uhm)
누가 말려 내가 좋으면 가는 거지요 (yeah, oh, oh, my God)

Ey! Oh, my God (He’s a really bad boy)
He’s a really bad boy
He’s a really bad boy
Ey! Oh, my God

He’s a really, really, really, really, really bad boy (ey, yeah, yeah, yeah)

You’re so bad boy
You’re so bad boy
You’re so bad, bad, bad, bad
Bad, bad, bad, bad boy

Bang, bang, pow
He’s a really bad boy
잘생긴 그 얼굴 하나 믿고 산대요
괜찮다면 널 내가 길들여 볼게 (boy)
Mine, mine, mine, mine

Ah, ah, ah (alright, hey)
멋대로 해 허락할게
있는 힘껏 나빠져 봐
Ah, ah, ah (uhm, no)
그런 니가 변해갈 때 짜릿하지 (oh, oh, my God)

Ey! Oh, my God (oh, my God! Oh, my God!)
He’s a really bad boy
He’s a really bad boy (oh, my God)
Ey! Oh, my God
He’s a really bad boy
He’s a really, really, really, really, really bad boy

You’re so bad boy
You’re so bad boy
You’re so bad, bad, bad, bad
Bad, bad, bad, bad boy

아까워 다른 이 난 못 줘
봐 내가 널 사랑하는데
누구라도 흠뻑 빠져버릴
You’re a bad boy, and you’re bad for me
You’re a bad boy, and you’re bad for me

아무리 나빠도 난 좋아 (you’re a bad boy, and you’re bad for me)
봐 세상에 넌 빛이 나 (you’re a bad boy, and you’re bad for me)
누구라도 흠뻑 빠져버릴걸 (you’re a bad boy, and you’re bad for me)
You’re a bad boy, and you’re bad for me
You’re a bad boy, and you’re bad for me

Oh, my God
