Cracks about facial hair, depth of her voice or size of her feet or any other "male like" quality seldom draw a woman closer to you
Agree to some extend but also disagree. See some women are very sensetive and some are not. Some can take a joke and some don't. It also has to do with how you tell the joke and your delivery that makes them love you or hate you. Generally anything regarding facial hair or body fat are conversation killers and should be avoided.
Here is an example of C&F I used on some girl I knew in College:
This chick tells me that she works out alot in the gym and she is so strong now (obviously we are talking about some petite feminine girl with big t1ts and tight ass, that can barley lift 5 lbs dumbell and is not working to bulk up but maintaing a curvious physique)
Me: "Really?" lets see how strong you are flex for me! ( i call her on her bullsh1t to control the frame)
She then flexes her muscle ,while I put my hand over her bicep and squeeze (to get some kino going) and say:
Me: Damn those arms are huge!! (saying it in a way she knows I am joking) are you doing the arnold schwarzenegger workout routine?? Are you going to start "TOOKING LIKE AHHNOLD"??
Her: Nooooo lol (a little bit offended but also a little bit intrigued cause she knows i am poking fun of her but haven't really crossed the line)
Me: I might just have to hire you as my personal body guard (mind you I am 6'3 200 LBS), care to walk me to my car? its a rough neighboorhood.
Her: Your silly ( smiles while playfully smacks me on the top of my shoulder which is the best indicator that my C&F was good and even though I made fun of her, it was pure jokes for the both of us).
Although the more you know someone the more you can and should get away with using C&F in the right way.
