Go for the desprate one.

You quickly identify a girl who has been using the app for a while but some quick math says she has made about 50 points a week and is surrounded by girls with 3 to 50 times the score. She is pretty cute too, short, long brown hair, dark eyes. Approaching her and taking the empty chair next to her as she fiddles with her phone. Her friends are all around but seem busy with their own business and you casually put an arm around her and but your lips close to her ear "Hey I'm dirk, nice to meet you." smileing at her she jerks realizing you are there. She smiles and brushes her hair over her ear blushing deeply she touches her phone to yours and you give her your number.

The two of you text back and forth for a while the music in the club far too loud for her to be heard. She is soft and warm as your hands explore finding her slightly baggy clothes to be hiding a curvy figure, though not fat by any means.
