So me and my buddy were out last night and approached 2 girls close to the dancefloor. Thing is we were not even trying to pick these 2 up (as they were 6s at best) So we didnt even run any material or try to bring then out to smoking area to run game.
But they flirted with us heavily. So was dancing with one and she was really grinding up against me (niether of us drunk). I went for her hand to lead her across the room for drinks, i squeezed her hand and she did back. I thought..."thats an ioi right?"

Well a little while later it turned out both of them had BFs. When we went home we facebooked them and they genuinely had BFs.
So why be a cock tease..... and is there any way of knowing a false ioi from a real one?

Thanks guys.
