I take it you're using Mystery Method.
Let's just say that you're using an opinion opener. For the sake of this post, we'll use the "who lies more" opener.
Approach set: "Hey guys, I need a quick opinion on something."
False Time Constraint: "I can only stay a minute"(body rocking)
Into The Routine: "...But who lies more? Men or women?"
I've found that the trick is playful banter. Poke fun, play around, etc. "No way! Well, I know she lies" "That is so cute!" (A la Lance Mason). Chat with them about it for a few minutes but cut them off after a while. It sucks when an opener runs its course and you're standing there lookin' like a faggot lol
You can't be afraid to interupt them. Girl A says something to Girl B, then Girl B says something; that's when you jump in with your next stacked routine (if that's the route you want to take).I personally wouldn't use the opinion routine. Everybody and their grandma has used it. Just gave it as an example. Anyway, hope that helped.
