HHV's Caramel Cappuccino does this...I didn't like the flavor at first so I set it aside for a month and when I picked it back up I was amazed...the first puff, I pulled away thinking that for some reason the liquid was getting in my mouth...the flavor felt like it POURED over ever inch of my mouth, it was weird at first and then I liked it lol It doesn't feel like vapor, it feels "wet" for lack of a better word and it feels thick...hard to explain, but this is the only liquid that does this that I have found.
