Yeah, you can more or less say anything, as long as you approach the girl in the right way.
It is a numbers game, and you are looking for a girl who you feel you have genuine chemistry with.
A tip: LOWER THE BAR AS TO HOW AWESOME YOU THINK YOU'RE CONVERSATION WITH THE GIRL NEEDS TO BE.
As Stephen said: going for a cold-read is good - "I like your style, I bet you do something creative."
Also, you can try:
"So, who are you?" and when she shakes your hand, pull her in and say: "Oh, Laura (or whatever), I love you!"
"Oh, my god, you're so huggable."
"I'm not even listening to what you're saying, I can't take my eyes off your lips, eyes, etc. they're so bewitching"
"So, tell me about yourself - give me the flash-bangs."
Remember: keep your eyes fixed on her eyes. That will help you to get turned on by her and, as we know...altogether now..."What you feels, she feels."
Speak slowly too, but with commanding tonality in your words.
PLAY TO WIN, DO NOT PLAY TO LOSE.
