Ok, these tips are more like spontaneous ice breakers that you say to a girl when you have established some eye contact.

First Tip

You established some good eye contact with a girl and you smile at her. Then you go up to her and say "Do you beleive in love at first site?" She should say "yes!" with glowing eyes, but then you say "If this were a movie I'd say so too, but this isn't".. then you go on with an opener, and you are good to mack on her.

This should shatter the ice.

Second Tip

You are walking, and you see a girl you'd like to mack some distance away from you walking in the opposite direction that you are walking in.... you establish some eye contact, and don't look away. As you 2 get closer, say "stop!" Then look at her as if your checking her out and say "damn girl! you look like you just got stopped by the man of your dreams!"

This should shatter the ice too if done right.

Are these field tested?

They sound way too canned, man. Especially the "love at first sight" one. Gets you off on the wrong foot, you'd think.

If it works for you

I would highly doubt that either of these work. Too cheesy. Best advice is to never use pick up lines.
