Memorise exactly the whole plumbing layout of the building then walk up to her and start explaining it in detail, I guarantee she will be interested. If she gives you a weird look it means she wants the chat up to progress to the city-wide sewage system. Be persistent. If she runs away follow her, it means your sewage system talk has worked and she wants to have sex with you and is making her way to a private area as quickly as possible for you two to ****.
You keep doing this and the guys will be so jealous of your mad skillz that they'll call the police to arrest you as it is their only way to compete with you.
'chat up lines' don't work g. nice clothes, nice scent, nice haircut. don't get too ****ed if you want to score as you'll make an idiot of yourself and even if you do you may well have floppy issues when things cut to the chase. also don't offer to buy girls drinks, firstly that shows you're gagging for it and secondly chances are she'll take the drink then **** off and you won't see her again. just eye contact, smile, then go dance with her. also i'd normally take a friend over cause girls don't like to look 'easy' in front of their friends and also friends can esily cockblock you so i find going over to a couple of girls with a friend or two works best. if you're not a natural dancer the best place to talk to girls is deifnitely the smoking area or whatever. and don't aim too out of your league (unless she's paralytic in which case go for it). and just remember to have a laugh and enjoy it, if youpull then good on ya but if not thre'll be hundreds of other nights! you're there to have fun so don't get broken hearted if a bird flips you off, just have a drink and a laugh with your friends. happy hunting!
