yeah, i agree with skills360, club game (especially on the dance floor) is non-verbal.
i use group theory when i approach a group of girls - you don't need a wingmen if 3 or more girls. if you dance with one girl then the other girls can dance with each other. if it's just 2 girls then one girl is left in the cold and she may cock block you.
anyways, when i approach a group of girls i make it interactive and have fun with the group but i'm not the dancing monkey. i have fun and dance with each girl even for a few seconds. i get them to welcome me into the group. don't go straight for your target cuz it's too mercenary. work your way to the target. you just need to open one girl from the group to get your in.
have you seen this thread, some good advice in it:
