Here is one of my personal plays I make after been chatting for a while, works on singles, up to groups of 4.

Example: engage by telling about how important it is how you feel when you interacting with other people, then say "there is something entising about your energy" (give a studying look). Setting up for the other to ask about hers energy, this is where you say something like; "yours I don't like, it's all sexappeal/sexual desperation/sparkly/bouncy( generally something positive)", or you can say something like "you have more off and aura, spilling out love/attractivness/power, are you some kinda alien? (here you can add words like weird or strange)". There are different ways to make this play, depending on the situasion, what you want with your evening, how big of a risk you are willing to take and how good you know them. If the group is more then two girls, you can play to girls as one; "The two of you, seperatly, have diffrent energies, but together it just explodes" (of course you should know if they are good friends, or just met).

Importent that you put an underlying tone of serious in the start, but then changing to a more jokingly tone

And after takeing her nummer, and giving yours. If she dosn't call or text me within 2-3 days, I send a text, "I am having coffee, expecting you bring your entising energy/powerfull aura"

Good luck trying it out and give response on how it went.
