If you're going to shame the OP, might want to get your facts straight.
The poster didn't say "flirty and funny". As nutso as the forum's censoring rules are, I don't think they'd censor the word "flirt". Use your brain.
Op, nothing wrong with your question. And yes,"c0cky and funny" IS a well-known(I thought) "technique" which DOES work quite well. It's what got me back going after a long lonely dark detour down the nice guy path. And what's great about that "technique" is it's not about pick up lines or coined phrases or methods so to say. It's about bringing out and developing a natural side of you that attracts women.
As far as additional techniques go, for me, I really built my game off of the foundation of C&F, mainly because that's what was most natural to me. I was that way any way, sarcastic, a bit of a good hearted **** talker. I just was that way with everybody else except with women...then low and behold, I found out I can be that way with women too. In fact, I should be that way with women. Point is, I would suggest, as another poster pointed out, find out what comes natural for you. The key is to be comfortable with yourself first, be grounded. Don't force things. Last thing you want to do is throw something random out there hoping it will connect only to hear crickets on the other end.
When learning how to flirt, baby steps. I would say the phrase "less is more" applies here.... until you really get comfortable with it.
