Girl: What are you doing?
PUA: Thinking
Girl: What are you thinking about?
PUA: How amazing you are
Girl: Really?!
PUA: No.
Playful. Always playful. If you can be cocky, insulting, and flirtatious in a way that is funny and playful you don't need techniques and routines, you can just flirt and vibe. The great thing about this style is its actually FUN, the whole process is enjoyable.
Also, "what are you, my girlfriend?" is not a good line. What would she say, "heh, uh, no guess not" or "heh, no seriously whats up?" It's just way too direct. What you're gettingn at is fine, but i suggest a different approach. like if she says something lame, in a funny playful tone say "okay, thats enough. We ARE SO broken up, i want my CDs back" or "I could marry a woman like you." "Really?!" "yeah, I'd divorce you a week later and take half your money." Just get creative. I am always testing my boundaries and thats what you gotta do. I've straight up asked girls if i started my own religion, would they worship me as their god. I mean ridiculous shit, but always in a funny way and it gets brilliant results.
PUA: You remind me of my dog.
GIRL: (angry, insulted but laughing) Hey!
PUA: What? I LOVE my dog.
This one is gold. When they say something good you reward them by patting them on the head, like you would your dog. There are no limits.
