Ever wondered why (most) girls like being busted on? Why do they giggle and smile at your comments? Is it because of the booger hanging from your nose? Does it wiggle to and fro? Hopefully not.

Yes, C&F lines create humor, mystery, a challenge...all those things that women crave.

But let's think about this.

If you were given a condom, and you never even knew that thing between your legs was called a penis...chances are you don't know how to use the condom to its fullest extent (no pun intended). But if you were a DJ, condoms wouldn't know what to do with you.

If guys could get girls in bed by solely using C&F comments, Chris Rock would be the President of the United States right now.

But I digress.

What's the difference between saying something C&F on the spot, call it busting on her if you will, and memorizing lines after lines of C&F comments?

The former came from within. When you said it, you really (not really) meant what you said. It was genuine. You exhumed confidence and anti-wussiness. You didn't focus on her so much as you focused on not TRYING to impress her with a C&F comment.
The latter was you TRYING to get a girl with a C&F comment, which shows you are insecure if that is all you do.
