Have your friend go on and brag about how you have this amazing sense about people (This is great because it's your friend bragging about you – not you bragging about yourself – learn more about disguised bragging at DatingWar.com). Tell the girl that you will ask her a series of questions that will let you know what sign she is. Make sure to say that you can't always get it but that you can tell someone's sign by the way she dresses, carries herself, by what career she's chosen, etc. Let's say her sign is Gemini. Have your friend look at you and say, “Go ahead”. Then you proceed to ask her some questions like:
What do you do for a living?
Do you believe in reincarnation?
Are you a creative thinker or more of a logical thinker?
Do you believe in love at first site?
What's your favorite color?
What are the 3 most important characteristics you look for in a mate?
Do you believe in soul mates?
These questions aren't actually revealing anything about her to you but if you seem to be genuinely asking, the girls will believe that you're really reading her based on the questions. Then to her amazement, you reveal that her sign is in fact Gemini. The whole group is baffled that you figured it out and now think you have some kind of mystical intuition. Women love anything to do with feeling and passion and mysticism. They'll think you are incredible.
How It's Done:
As soon as the girl tells your friend what sign she is, he says a short phrase that indicates to you what sign she is. The first letter of the phrase corresponds to the first letter in the sign name. For example: If she's a Gemini, your friend will say to you, “Go ahead”. If she's a Pisces, your friend will say, “Pick what sign she is”. For most signs, the first letter of the phrase you use is enough. For some you'll have to go by the first few letters because several signs start with the same letter. For example: For Aries you'll say, “Are you ready?” to your friend, while for Aquarius you'll tell him, “Ask her some questions”. Just memorize this stuff with your friend before you go out and it'll become simple. You can do this again with a few of the other girls in the group. Make sure that once your friend says the brief phrase, he stands somewhere behind you and out of the way so they don't suspect signaling of some sort. After doing it with a few girls, they may find it suspect that they have to tell your friend each time before you start asking the questions so you should probably limit it to reading only 2 girls at a time.
