C+F is not a tecknique, its a theme. If your end of the conversation is C+F that means you deliver every line you say like you've said it a million times before, and you still love it. Whenever she opens herself up lay on a 'yeah, I know I'm sexy' type of line. Leme show ya a C+F convo/interaction:
Anthony GRRR - Hey K
K - Oh hey, wow, Anthony, your all grown up!
Anthony G - Well thats one of us... but what have you been up to?
K - Its SUMMER! Relaxing, tanning, working unfortunatly, and lots of hot passionate sex
AG - So you've been sleeping, baking, flipping burkers and making love... to yourself? Sounds exciting!
K - Oh if you only knew... and whats been keeping you busy?
AG - Well I got a new hobby
K - Anal Sex?
AG - Close, dealing arms, actually
K - IC, and how's that going for ya?
AG - Not as good as that gig @ Chip/Dale's [male strip club in buf], but it pays the bills
K - Wheres REG?
<blabla, fast forward to the car on the way to the theatre>
K - I gotta tell ya, Anthony, you look good
AG - Awww K, thats what all my friend's sister's say!
K - But do they all drive you to the movies?
AG - Well I usually bill them by the half hr for my time...
K - You remind me of me... only I bill by the hr and round up <devilish grin, I got wood>
<I'm tired of typing>
Thats C+F... going with the flow and having fun with the girl your talking too, letting her know you know you're sexy. Its not one line, its just rolling with the punches, making her roll her tongue in her cheek trying to find a cleaver comeback, but she cant cuz shes too busy smiling.
