The balance between cocky and funny is essential in order for the technique to work. This balance is personal, everyone has their own way of doing it. In my case this is what I do, first I think what I want to say, then try to make that funny and then add the cocky part. It works for me. Remember, C&F varies, it depends on the women but more importantly, it depends on the connection you have with them. The more connected you and a women are, the easier it will be to make C&F comments!

Day Game Questions:
I'm not that good at Day Game, but here's my advice to you.
1. I wouldn't try to stop a moving target, there are to many situations for the girl to be moving, and probably those are important. But, If you really want to, you can do this: Walk casually in the direction the girl is coming, and make eye contact with her, if she keeps the eye contact while you are walking towards her, and she towards you, then it's on. When she passes you by, you can walk backwards a bit, and say to her: "Hey!! Long time no see! How have you been?" (Familiarity Opener). After this, you can engage on a conversation about you mistaking her for somebody else.
2. If you say you look like 35, then you should work with your image. Go to the gym, or go jogging everyday, get some new clothes, shave, etc. Try to look your age first. If you gamed a teen and wanted to get out of there, you could just pretend to have recieved a text and make up an excuse to leave. Hope this helps.
