I just made up a new opener, might try it tonight

What do you guys think:

"Hey, are you bisexual?" and maybe add: "because my friend over there thinks you're not, but I think you are"

If she asks why just neg her, e.g.: well, You can always tell which ones the lesbians are. (insinuating she looks male).

And from there on, I've always had this theory that EVERY woman is partly lesbian. Some are 100 procent lesbian, some 50 pct, some even maybe 5, but every woman can be attracted to another woman at one point or another, it just a matter of acknowledging it. Although, that might be boring for her right after the opener. Might wanna explain that later on

So?

I think that's a pretty good opener in a club environment. It immediately stokes her curiosity, and is guaranteed to get a response. Good work.

Jep, that's what I thought. You're kind of touching their 'pride' by insinuating that she's gay, so even if she's not immediately interested, she'll have no other choice than to respond, otherwise she would just confirm that she's gay.
