Thanks for the encouragement/method.. Have ignored twitter for some reason even though I have heard about its potential for such a long time now. For those still needing twists:
Follow M2S example and find a hot girl picture for your profile, preferably one with a shot of their body in great shape. Although you would think this would be to attract men, women often will friend good looking girls just the same.
Use a cpa offer for free samples of some kind of weight loss product, (would use something other than acai berry just because of saturation with it these days) add that to your profile. Than just tweet normally with variations of "I am out eating", "Love the dessert at ....." etc.
Envy is a powerful tool, and visiting women will look and see a perfectly shaped girl that seems to be "always eating". How does she do it comes to mind quickly, and they will check out anything involved with getting that same body because they will want to find out how.
Have seen my girlfriend do this so many times between myspace and facebook, with girls she doesn't even know. You are actually preselling with you picture without saying anything.. a subtle push to find out what you are doing.
Create your own twists, take any offer and figure what interested people would be intrigued by and do the same thing.
