Roissy/Heartiste touched on this yesterday.

The example given in the blog is when a woman asks you to hold her drink, which is a shit test. Shit tests, aka fitness tests, are really just a form of breaking rapport on her part, and as a rule whenever women give men a rapport break (which is what a shit test really is) the default response should be a rapport break of your own. This is the core essence of how you handle shit tests. Three of more common forms of this are:

  1. Agree & Amplify (to absurdity)
  2. Change the subject
  3. Ignore her

All three of these examples are varying degrees of breaking rapport. The quip he made about polishing her slippers is a mix of 'agree & amplify' and 'changing the subject'.

It's important to note that whenever you deliver a rapport break of your own, that you should follow it up with some form of comfort. The longer you wait, the more you'll need. Sometimes simply giving a wry grin can be enough so to indicate you're being flirty & playful and not a real asshole about it.
