It most commonly comes after you've well established your frame and passed multiple shit tests as woman's weapon of last resort. What makes it so dangerous is that unlike other tests, this one is being delivered in a pleasant tone, when you're relaxed and it sounds like a genuine praise. Some women will also be looking at you with curiosity and admiration, almost as if they were looking at a magnificent statue. This will make you incredibly keen to drop your frame and victoriously start explaining yourself how you actually are this and that... which is the worst possible reaction. If you fail this shit test, you can expecte everything you said to be used against you in many more, less sophisticated, shit tests to follow.

After a bit of trial and error, the best response seems to be no response at all. Slightly raising your chin and looking to the distance appears to work well too.
