First time in a club

I've been avoiding these because the idea is retarded and there's no reason to go there when we have pubs for us civilised people. Now I have to go. Is there anything I should know? Like about the handkerchief code in the pub.

handkerchief code

Is that the sign gays use for one night stands?

The only advise I'd give you is try and get blotto before you get there so that you dont pay rip off prices. And of course DANCE.
