I know that opening is pretty much the most useless part of the game because you can say anything like Hi to open. But theres 2 that I've been using a lot lately with good results that you can transition from easily.

First is Style's own but It's only on youtube and I dont think a lot of people know about it. This is a good one to ask one person or two people(easily leads into best friends test)

You: Hey ladies I need an opinion on something. I'm going out with my friend (Name) to the mall (tomorrow if you're in a club/later today if this is during the day) and we're looking for a (whatever type of clothing) for his gf but we don't know her size and we don't want to ask...is it better to buy a size a little smaller or a little bigger?
Her: Blah Blah
You: (Doesn't matter what she says just disagree with her and mention how everyone else you've asked said the other one) I guess i'm asking the wrong person...look how you're dressed(BIIIIIG Smile)

If you delivered it right she will laugh and hit you a little but that's all good. If it's one girl you can transition easily into something about the mall like a story or another question. If it's 2 girls, best friends test...if they give the same answer or different it will still work

Second is my own:

You: Hey ladies I need an opinion on something...my friend(name) just started seeing this girl and he said everything is going well but she won't tell him what she does for a living..should he be worried?
Her: (Now almost everygirl I've asked has said either hooker or stripper or something along those lines)
You: Wow, you seemed so sure about that...is this something you're familiar with? (Neg-smile)
Her:Shut up!
You: Haha, well me and my friend were just joking around that it could be that but you really think that's what it is?
Her: Oh ya/I dont know what else it could be
You: Maybe she's a spy and would have to kill him if she told him
Her: haha maybe

Now transition into something...best friends test again if it's 2 people and if it's one person you can transition into a dhv story or 5 statement game is good but you might have build some more comfort for that

Thanks for the post, I'm loving both of them - I'll have to try them out myself

They both sound great, I will give them a try and see what happens!
