man u should have gotten her some icecream but not until You had a candid sexual discussion about icecream
Involve cherries, strawberries whip cream, banana's, etc.
the convo should've have gone something like this.
Girl: Hey could you bring me some icecream
You: Ah!! So u like icecream huh(say it smoothly )
Girl: yeah i like cream i like vanilla(or whatever she says)
You: Vanilla well thats a good icecream..
You: do u like strawberries
Girl: yeah i like strawberries
You: Ah ok i see hmm and Whip cream
Girl: yeah i like whip cream
You: Hmm Well I know u like strawberries but how about bannanas do u like bannanas?(While ur saying Bannanas u adjust your junk Don't grab yourself put ur thumbs in your pocket and give a slight pelvic thrust forward while giving her a smirk)
if u said this right the girl should laugh
You: (Pause look at her shocked) Whoa U Sick freak!!! I'm talking bout icecream. Stop thinking about that all the goodness down there look me in my eyes.
You: I'll tell u what I'm going to get this icecream an I'll u call u later.
When she gets over your place u want too make some moves to be licking that icecream off her neck and body
Lastly don't let the so called PUA rules overcome rationale thoughts
I saw opputunities. All u saw was I'm NOT PAYING!!! I'll look like a chump
you've actually hung out with this girl a few times its not like u just met her like i said you could have used this situation to your advantage
Next time if getting icecream comes up. U could easily turn the topic sexual
