谢谢灰衣人提醒，我查了查字典

1 : behaving badly — used especially to describe a child who does not behave properly or obey a parent, teacher, etc. ▪ a naughty [=bad] boy/girl ▪ Were you naughty today at school or did you obey the teacher? — sometimes used humorously to describe an adult who does something slightly wrong or improper ▪ I was naughty and cheated on my diet.

2 informal : relating to or suggesting sex in usually a playful way
▪ She gave him a naughty smile. ▪ No naughty [=dirty] jokes in front of the children, please! ▪ a naughty outfit

在我用naughty的context下，应该不会有歧义吧。
