When I can't think of anything else to get things poppin, I always fall back to the "lemme give you a massage" line.
After doing that and feeling on the female it usually lets me know what she is about.
What do yall have?
Whip it out
I usually just play it by ear, but usually I try to push up on her, but not too aggressive, pull her close, and try to get her feeling all warm and fuzzy by kissing her on the cheeks and saying stupid sh*t. Once and if she gets all warmed up...

I don't know if there's a go-to move, you can break some chicks down with music, some chicks down with a good convo, some chicks with some physical activity (walking, beach, etc), whatever let's you get close to her is the proper go-to move for that chick. Generally however, across the board, you can never go wrong with tickling/pinching her sides quickly. It breaks the physical barrier in a playful, non-aggressive way. If you can get a reaction out of her (i.e. her tickling you back), use it as an excuse to get a little closer each time.....
but enough of this, y'all ain't payin' me.
