Like what the people that posted before me said, basically just tease and think of it on the fly, but i will give some examples from A2damir's FRs who I think is really good at C&F. (Its one of his main tools) So here is a little piece of one of his FRs where he was gaming a chick.
Me : ( i reached in my pocket and found a coin) Heads or Tails?
Her: ( looked at me wierd) what?
Me: First of all its EXCUSE ME and not WHAT!...anyway i said Heads or Tails (and i showed her the coin)
Her:heads
Me:ugh! get your head out of the gutter will ya?
Her: (laughed)
i tossed the coin, and it came as HEADS, so i flipped it around on purpose (and let her see that i did it) and told her
Me: Tails, sorry
Her: i saw you cheat
Me: your not gonna go down without a fight huh? you lost its over, get
over it. i might give you another chance to win later on
Her: what was the prize?
Me: if you won you couldve bought me a drink, but you lost
Her: ( she really laughed at this one...armor down to 80%)
Me: you want another water?( and i pointed at her ****tail)
Her: its not water
Me: this isnt high school you dont have to impress me and try to be the
cool girl who drinks… what are you drinking?
------------------------------
I will paste a few more
Me: you smoke? That’s gross
Her: (just looked at me)
Me: you watch MTV?
Her: yeah
Me: NEXT
Her: (laughing, and told her best friend that I nexted her)
----------------------------
Her: do you have a phone?
Me: no I usually write a mail and have a guy with a horse deliver it
…of course I have a cell phone
----------------------------
Me: hey get up
Her: you wanna go to the bathroom?
Me: no, don’t even think about stealing my chair
Her: oh your leg got tired?
Me: no I was getting a hard on
Her: (she actually laughed very hard at that and then smacked me in my shoulder) your such a **** you know that
Me: I'm not all ****, but mostly ( with a wink)
Her: (she pinched my arm …which BTW both were IOIs..cuz she was doing them jokingly)
