A theory consisting of two equally complex stages, both completely dependent on the other. And, if executed correctly, this formula is 100% effective. The objective of the formula is, of course, to get laid.
Phase 1 requires that you introduce yourself to a member of the opposite gender in any manner. A handshake of brief conversation about the weather will suffice
In no more than 24 hours later, locate the same member of the opposite gender, remind her about your brief introduction, and she will, without exception, go into a fit of sexual desire and fuck you immediately.
"Yo man, I'm going to fuck Pele tomorrow. I just introduced myself tonight. It's my Theory of Introduction"
