Ladder Theory examines the relationship between men and women as both friends and fuck buddies:

Women seem to especially like it if you are more devoted to your bad music, biker gang, forearm tattoo or marijuana. These all seem to work wonders. There are some interests you can show in a woman that will help you to fuck her: a healthy interest in destroying her self-esteem and in fucking her friends more than her seem to work wonders. Note that the following topics of disinterest have been field tested and shown conclusively not to work: Unix, literature, poetry, international politics, and sodomy.

Novelty - Let's face it, if you're like every other guy who works a normal job and tries to live a good life, you're probably like just about every other guy. Chicks don't dig this, and why would they? Who wants someone who is just like everyone else? Something different is more attractive. Like someone who does not have to work during the day like most people because they have lots of money from business or selling drugs. Or like someone who has stabbed a man and went to prison for it. Different and a veritable ticket to getting laid.

So it should be self-evident, if you are following this at all, that the people you want to have sex with the most will be at the top of the ladder. Descending down to the bottom of the ladder we pass the following people:

1. The people we really want, who may even be out of our league, are on top.
2. Then come the people we like.
3. Moving further down we pass the people who we would fuck if we were intoxicated and would admit to doing it later.
4. At the bottom are the people we would fuck drunk, and would lie about doing it later.
