How I was cocklblocked in disco and what would you do?

[partytillyoung]

So that's what happened. I was at disco and there were 3 girls dancing, I approached them and I introduced myself to every girl and then I asked one girl for dance. She started dancing with me for like 6 seconds, then I was cockblocked by her friend. She said that's my special friend and I didn't know what do to, she just blocked me, that's why I move on. It's kinda hard to do when you are alone with 3 girls , I have no problems trying, but it's kinda stupid. Almost always some "friend" block you. Because she's angry that I didn't picked her.

What would you do? What are the ways to cockblock her back . I know something about leading her to other place, even if it's 2 meters away, but the girls wouldn't probaly allow her.

Thanks for help
