These are a few tricks I use and they work all the time.

1. High five- Tell a girl give you a high five and move your hand and say "to slow," they usually try and hit it again and get interested.

2. Nicknames- Take their name and give them a nickname from it. For example: Amanda HugandKiss(immature but girls crack up). Or something that rhymes with their first or last name.

3. Wave- Face the girls direction and wave behind her and look behind her. She will turn around and if in the right environment will see nobody and by the time she turn back to you she will see you pulled a joke on her. If a girls already taking a good look at you while you do this it is a killer.

Anyone else have contributions?
