I don't get it, guys. Yes, I know the theory behind it and I know what i'm SUPPOSED to be doing, but I can't connect the dots between me reading about it and doing it in real life.

Everyones talking over each other, girls are in packs 5 large and guys are fighting over them.

How am I supposed to open without feeling like i'm hounding or intruding? What does an open even look like? I'm going to look pretty weird using a pick up line or just walking up and saying hey to a girl who's being approached by several guys per minute.

Also, what on earth could I possibly say to a girl in such a loud place to hold her attention for more than 5 seconds.

I know these questions are noobish, but bear with me, i'm new to this and it's overwhelming me. I get nervous in certain situations and I can't see myself going up and saying something solid and interesting in a clear voice and not letting guys cockblock me or the girl lose focus.

Edit: Thanks for all the different responses. I'm going to apply myself again tonight and go have some fun!

Edit: Went out tonight and picked a random lonely guy to be my wingman and brought him into a random club and we hit on like 1000 chicks and got rejected and we are going back tomorrow. This is so fucking awesome!!!
