i usually say: "so how spontaneous are you?" in a confident + cheeky smiling way
HB will probably say: yeh im spontaneous or i am pretty spontaneous
(its rare for her to say no because that would mean shes straight up admiting shes a boring person)
And then my follow up question would be:
"okay lets find out, if i asked you, are you a down to earth girl, would you say yes or no?"
Again she'll shyfully say yeh i kinda am or yeh i am
Then you can do alot things after this. Go for the Kiss close or number close or isolate her, or ask her to go somewhere with you right there and then, have fun!
Most importantly its your frame and not hers so you have her hooked to you
