okay I'll list all the IOI's I can think of off the top of my head... While drunk.. :p
- Assuming attraction. Always do this, it solves a lot of shit and often puts you in the mindset to 'just go for it' when you really need to.
- She fiddles with her hair a lot when talking to you.
- She stands with her legs crossed.it means she doesn't plan on going anywhere.
- She stares only at you and doesn't look around.
- She asks for your name before you ask for hers.
- She starts qualifying herself and giving you reasons why she's a good person.
- She fiddles with her clothes often when talking to you.
- She touches you a lot when she talks.
- She asks for your number (duh..)
- She laughs at unfunny shit. Also a good test to see if a girl in a group likes you is to make a really edgy joke. The ones that laugh a lot like you.
- She stands inside your 'comfort zone' a lot when talking.
As for building attraction, that's fairly simple once you have their attention. All you have to do is be able to talk shit and build rapport. My personal method is to brag a lot and come across as kind of arrogant or even rude in a cocky/ funny way. For example, the other night a girl I was trying to get with wasn't out when she said she would be so I sent her a text. This is the exact convo.
Me: "Oi! Whoresack! where yous at?!"
HB: "What..? I can't get anyone else to come out. and who you callin a whore?"
ME: "pffft alright calm it. You're still a wuss though, you're never out." (refference to previous joke)
HB: "I caaan't no one is ouut"
Me: "I'm out"
HB: "and?"
Me: "And what? Just come out. You never know what might happen!

"
HB: "Fiiiine. Meet me in the smoking area when I text you"
I slept with that girl that night. She agreed to come to the club on her own just to see me... Just be super confident and arrogant in a tongue in cheek way, I find it easier in text because you can think about what you say first. But if you're good at it it works just as well, if not better when face to face.
