i think thats the only problem in clubs. the music is too loud!
how can i go up to a girl and end up shouting at her ear to ask an opinion on something..

Believe it or not, people do pull at clubs.
Try opening outside in the smoking area or at the bars. On the dance floor, open by giving hi-5s, gesturing, being dominant. I don't use opinion openers on the dance floor!

Watch tim's rsd flawless natural dvd it's got a bit about dancefloor game. You have to be 100% committed though it's stuff like walking up to a girl grabbing her and spinning her then dancing with her, pretty ballsy stuff.
K and jynx might be able to add a bit more to this kind of thing

Yeah, forget long drawn out openers or conversation I'd say. This is all about body language and facial expressions conveying your intentions etc. There's also dancefloor game.

Sapmi is right about the smoking yard. I've been hanging around with him in these recently and it brings about great opportunities to chat to girlies.

duuuuudeeeeee clubs are easy
you just walk up to them and pull them do the talking later because the chicks are dancing and having a good time as long as your energys good and you smile and approach with intent all is good

Girls go to clubs also to get men. This shouldn't be so hard. The smoking yard should be full of girls waiting for someone to get them. And when you're on the floor, let your body do the talking.
