I think these guys got it all wrong. You need to do the opposite of what most of these people are saying. Get fit? Don't drink much? WTF?! Isn't that why you play? To drink with your buddies. And, don't you need a drink, or six, to relax?
Well... I say what you need to do is join a league, but make sure nobody knows you. If you have to travel a 100 miles so be it. It is critical that nobody knows who you are for this plan to have any success.
Next you must look as pathetic as you can. Wear stupid/dorky clothes, clean not smelly. Messed up hair, anything to stand out from everyone else. Be loud, but not obnoxious(rude).
Buy the newest trendy gear. The more it stands out the better. New cue with a new carbon fiber shaft and a JB custom leather case with your name all over it, full of every pool contraption known to man. Buy a glove for both hands and make a point to ask people why they don't sell them in pairs like other gloves. Get the most expensive chalk you can buy.
Be boisterous, loud and fun. Girls like outgoing, fun guys.
Here is another critical part of the plan... you need to play the worst pool of your life. You need to struggle just to make a ball. To make two balls in a row would be an amazing feat for you. Dig deep, look as pathetic as you can. Don't get upset or angry. Pool is not the goal. Women, is the goal. They don't like guys with anger issues, so no getting upset. Maybe just a little frustration, but no tantrums. This will demonstrate your self control, which is sexy to females.
Hopefully, some girl will feel so sorry for you and they will try to help you. The other guys are just going to laugh and make fun of you but the girls will have sympathy. This is your "IN". Use it. It doesn't matter if she's one of the attractive ones or not. She'll have attractive friends hopefully. Odds are they will send the least attractive one over. The other guys aren't paying attention to her anyway. Be extra nice to her. It may only be a test to see if you are worthy of one of her other friends. Either way, now you have choices.
Best of luck!!
