Is to ALWAYS spike the attraction (or flirt) every day, even if it's just some corny line like, "Um, excuse me miss, I thought you were lookin' mighty fly from across the room, so I just had to come over and see if I could get that number."
Yes, you've been dating her for a while. Yes, it is corny. But I have noticed they eat it up and enjoy the flirting.
I do this with girls that I just kick it with when they've dressed up really nice for the night and they enjoy it.
Keeps it playful and flirty. Girls always eat it up even if they poke at you a lil for being corny.
