What Does Sexy Mean to 6-Year Old?

As much as I tried to make sure kids did not hear innapropriate songs, I could not hide them all. "I am sexy and I know it" was sang by a classmate of Kyra (K-n!), was shown on TV in Madagascar.. Kyra heard it and asked me if "sexy" was a bad word. Oh boy. I tried to say it is for adult use only. It is not a bad word but it is not for the kids to use. It means when adults say to each other that they want to spend some time with each other snuggling, kissing and hugging and may be even making a baby (she missed that part, fortunately). She listened, said Okay and that was it. Phew.. Till the next time...
