Mirotic(K&J-pop group singers' song)

This word was now to me. So , I checked out this word on the net. "Mirotic" is a coined word. "Miro" is Korean word which meands maze, and added English "ic".

I've heard that it's banned and deemed inappropriated for 18 and under 17.
I wanted to figure out what parts are inappropriate, so I watched this song on You-tube for many times. BUT I could not find any..........my English is betting worse . hahaha!
