C'mon GFY.. surely we can do better than that...? Where's all the great strategy and lines?!!
Ok i'm kind of ashamed to admit it, but i've come up with a line that
Really works... every time, if well-delivered:
i once was talking to a woman who was really hot. So hot, that she was throwing me off my game a little. i kept noticing how hard it was to look at her, and not get distracted by her appearance.
So while she was in the middle of some story, i just blurted out, "Sorry, i can't look at you... you're just too hot, and i can't concentrate on what you're saying" and turned my head in the opposite direction. As I said it, I also put my hand up in between her head and mine, as if to block my view of her. Also, did my best to seem embarrassed or uncomfortable about it.
The longer i kept my hand there, the more she giggled. We kept talking, me looking away, and her talking to my hand... and it was ON.
That first time was cool, because it was spontaneous and fantastic in that moment. But i'm cheesy, and i've created that same situation a couple times since then

with women i didn't even think were that hot just to see... it worked, every time, but never as well as the first.
