This one time, I met this girl with a strange sense of fashion. She had these wacky pointy shoes that were striped, and instead of affirming her style and therefore her personality, I bugged her about it.
"What's with the shoes? They make you look like that witch from the Wizard of Oz."
(At this point she's thinking, "this guy isn't complimenting me... what the hell is he talking about? doesn't he like/appreciate my style? where's this going?)
She muttered something like, "What's wrong with my shoes! They make me look like a witch?" Most girls peak in interest and curiosity when you start to deviate from the trend right about now. They start to wonder. They'll often set themselves up further. They let you try to 'correct' what you just said, as if you slipped for a moment. But keep giving it to them, while smiling.
"Yeah, wizard of Oz, that's it. I can see that sortof style in you... Oh man... I bet you wear that poofy grandma witch underwear too... that's hot."
(Basically, she gets flustered and doesn't know what's going on. She's getting teased, but most guys compliment her and appreciate her style..!? This is great for kino and all that stuff. It's disarming)
Now, that's definitely not the smoothest example, but it's the most recent experience of mine. Hope it helps explain the C&F idea.
EDIT
As the convo went on, I kept ragging on her style in a friendly way. It undermined her style, and implied that she was a bit goofy and that other people might get a laugh from it too. But I reinforced it too, with something like "But you know, I like it. It's different." So in that instance, it was devaluing her a little bit, so that later on I could wait for her to try to qualify herself. Then, by affirming her a little bit, I show that she has some value in my eyes, where other people might giggle. Push, pull.
But there are better examples of C&F out there. I'm still quite a rAFC. Check the C&F section in DJB.
