MPI 

Marriage Proposal Index. A simple statistic ranking your ability or plausibility of getting married. You get points for all sorts of things, based on your culture. In America, its probably mostly due to money and/or fame. In other places, social status. Sometimes based on profession (doctors can get married easily).

MPI guy 

Minimal Possible Investment guy.

An MPI guy is a player who is only interested in stringing you along with the minimal amount of effort required to keep your hopes up in order to stroke his own ego. If you have an MPI guy in your life, it is time to get ruthless and cut him off, because he is stopping you from meeting the world of guys who actually have potential. See that MPI guy for what he is, and kick his ass to the curb so you have more room in your life for something special to come along.
