Yeah he's making fun of her. (Was it the watch-check that gave it away? ). In his defense she more than half deserves it. I bet she regretted drinking that much the next morning (assuming she even remembered it). But if you look at the dancers in the background, some are doing lead/follow and others are just freestyling. In a mixed venue like that, you can't expect any rando you pick up to have the idea of lead/follow. I'd say if you are dancing with someone who expects to freestyle you should just do so right along with them. You can't lead someone who doesn't have the concept of following.
