Gentlemen,
Three days ago, something pretty sweet happened to me. Now, I'm by no means an expert PUA, buut I dabble
My ex-girlfriend's best friend ( a 9 for sure) (I'll call her J) just broke up with her boyfriend. She was upset and she wanted to talk, so she hit me up on facebook chat at about 12:30 in the morning. We chatted for a little bit, then, just for entertainment's sake, I invited her out for some coffee. She agreed. We met, walked around a little and then went back to her place. Kept talking. In the middle of casual convo I found out her heritage (Polish) and here is how I proceeded.
ME: Haha (laughing at prior sex-related joke), you know J I read somewhere that Polish girls are terrible at making out, like they just don't get it , they don't know what to do.
HER: (Half offended, half smiling look on her face) Nooo we're not, we're like the best at it!!
ME: Eeeeh I don't know, I don't always believe what I hear. I have yet to be convinced (leaning back with a sly smile)
HER: Oh really? (Grabs my hand and starts making out with me) How was that??
ME: Not too bad.. But my dog can do better. (Then I did the whole kino to face and hair routine and kissed her for about 20 minutes).
Then the even more fun part happened. I finally went home around 7 AM.
SO. Once you hit her with the 'I have to be convinced' line, there are a few ways she can respond. One is the way J did, in which proceed as above. Another is something like this: Psh I heard ____ (your nationality) are terrible at making out! In which case you can come back with something like: Well, I guess there's only one way for you to find out now, isn't there... Or if she says that she's not going to or doesn't want to kiss you, take a page from Mystery's book and be like, hey now, I didn't say you could, I just said I read about it.
Hope this helps. I'd love to see someone else try this and share your results. Mine were pretty damn good, I'll tell you.
