There's an awesome app called Bang With Friends on facebook that I think revolutionizes online sarging.
Basically you pick among your facebook friends who you want to bang (the friends picked don't know about it), and if that person picks you back, you both get notified by the BWF system and you guys can hookup.
Problem is...what if you don't have a lot of friends on FB?
Here's my idea:
1. Enter in your city in Facebook
2. In the search results, click on the FB page for your desired city
3. In the FB page for the city, click on the number of likes the page has. It should bring you search results of all the people who liked the page.
4. Adjust the filter to your liking
5. Friend Request the HB's
6. For the HBs' who add you back, mark them as "down to bang" on BWF
7. Add the HBs' FACEBOOK email addresses (*facebook username*@facebook.com) to your email's contact list (gmail, yahoo, hotmail, etc). Use an email account that does not give a clue that it links to your facebook account.
8. Use the "Spread the Love" feature in the BWF app to anonymously promote BWF to the HBs' facebook emails you've just added to you email client.
9. Wait for the pussy(s)

10. Get Pussy
11. Repeat
What do you think?
Edit: Added in steps to account for most girls not having the app.
