An index describing the level of "Polak" in a given sentence. Perhaps best used by Michael Scott, Regional Manager of Dunder Mifflin Scranton, in a lecture given to a local business school in Scranton.
Business School Student: "How has your Herfindahl index declined since the merger?"
Michael Scott: "Nice try. How's your Polak-says-what-index?"
Business School Student: "What?"
Michael Scott: "Thanks Kowalski"

How far a given human being is from fresh hot bacon. This index value is an indicator of quality of life in both first and third world countries.

the BPI is the product of a number of variables

The score provided by the remaining members of a game or group, after a butt-hurt member departs with a Rage Quit. Typically a 1-10 scale, with 1 being low, and 10 being high. Scores are subjective, but based on the veracity and vitriol of the departing member.
Butt Hurt: This Facebook group used to be great, but all of you racist, homophobic, misogynistic, fascist, and xenophobic assholes have made it unbearable! I hope you all get cancer and die!

Remaining Member: Rage Quit Index (RQI) = 2/10. Quite a cliché since the #2016Election. Needs to get some original material , but at least they we're passionate.
