What is a eg or eg hit or eg theory?
It’s an approach/attract theory from Mystery. A negative remark towards a girl designed to break her indifference to you by showing her that you are indifferent to her beauty (or other striking features). Not an insult, that would be bad. More like “Those are interesting nails – are they real?” or “It’s really cute how your nose wiggles when you talk – look, there it goes again!
