Unfortunately I don't have an original phrase but here goes:
Wow, you have a great amount of balls to be so free

Props to you. I can't even karaoke in front of strangers hmm.

let alone dance... I tried "free dancing" one time & my ex-friend made fun of me so I stopped dancing.
If you were located nearer I'd have you at a party sometime but you're not.

Anyways, interesting dancing.
