Step One:  Approach Ball Girl and initiate conversation. Pray that she has low standards.  Then quickly approach her from behind while she's working so that she can't be rude to you or run away. It is integral to get down to her level before you get down.  Spread feet in wide stance to get maximum balance.  Bend over and lean on the wall to show how comfortable you are. Relax and smile. Use your body language to give signals that you are the fun person that you are, and to show that you're comfortable and confident. There's nothing to be nervous about. Raise rump high into the air like a baboon. Say something clever and non-threatening like "You must really like to touch balls!" Then let out a huge belly laugh, this will set her at ease.

Step Two: Prepare to fight off your buddy who is trying to c*ck block you. When she stands take an open stance so you can fight off other interested males while still giving her the appropriate attention.  Once the males know that they cannot sneak up on you they'll likely surrender the prey. Never take your eyes off of her, staring is an important part in the mating ritual.

Step Three:  Use body language to hint at your romantic intentions. Once all competitors have been scared off, step directly in front of her line of sight and flex your pectoral muscles.  Alternate between left and right if possible.  Sway hips forward and backward ever so slowly. Make sure that the fly on your pleated slacks is open to give her a peek of your goods.

Step Four:  Close the deal. Ask her if she'd like to sit on a comfortable padded wall.  When she has exposed her back to you she has submitted to your advances. You may now put your arm around her or feel her up.
