So in a loud dance club/festival environment I'm wondering what direction one takes for verbal interaction.

Case example: Dancing at festival, cute girl with nice booty moves in front of me and doesn't really say anything or even look in my direction. Is basically grinding her back toward me and so I put my hands on her hips but nothing is said. I feel like she may have wanted to further the interaction but after about 4 minutes she runs off elsewhere. Just wondering if there's something I could have said or done differently in this situation that would have furthered the interaction.
