Some guy asked basically the same question a few weeks ago, and I gave him the same advice I'm going to give you.
In the DJ game, standing out in a woman's mind is what boosts her interest level. That's why "neg hitting" works so well on 9s and 10s--they're used to guys waiting at their beck and call 24/7. To get with a Hooters girl, you have to separate yourself from the scores of other horny chumps who frequent that establishment and try to get laid.
That being said, using "tricks" to pick them up probably isn't going to work, because they've already heard every trick in the book. They've heard the cat calls, the "God damn baby"s, guys boasting about their careers/money, etc. Judging by your post, nothing you've tried is new to this girl.
Try having an everyday conversation with her in which you don't appear to be trying to "pick her up." Actually talk to her as if you assume she's an intelligent person. Ask her about any books she's read or good movies she's seen. Have a conversation in which you talk about her interests. Then close with a genuine "it's been great talking to you, maybe we can continue this over dinner sometime. Can I get your number?"
Then report back to us and tell us if your progress has advanced.
