As the title implies, I have little trouble approaching, DHVing, kino-ing and number closing on the street, bus, bus stop, grocery store, etc.

However, I get blown out of the water every time I step into a club. I'll often be with a group of friends (mixed set) but have serious trouble having women from other sets dance with me. Even if they are receptive, i'll often get cockblocked by her fucking friends.

I've read a lot of posts but very few describe the process of going into a loud club and grabbing a girl to dance with. Is it most effective to approach the ones at the bar or grab a girl dancing near you? Assuming it's super loud, how can a guy non-creepily start dancing with the chick?
