Get the Flumping mug.
A flump (fl-uh-mp) is generally used to describe a woman, whom at first glance, is considered to be very unattractive/ undesirable, ugly, disgusting, and mostly someone whom you would not sleep fuck with. However at a second glance, nearly immediately after the first glace/ initial reaction, you have a sudden realization that you would indeed still have sex with her and/or "wouldn't kick her out of bed".
"That girl last night was a Flump for sure ."
"Your sister is a Flump surrounded by trash ass bitches."

A phony baseball metric which is an acronym for Femoral Leverage Under Max Pressure.

Many genius baseball minds within the league use FLUMP, as a way to discern which pitchers which eventually become injured or innefective throughout the course of a season, or a career.

Mike Rizzo, Billy Beane and Rick Peterson are a few FLUMP's largest proponents.

It is the most esoteric of all the sabermetrics to be sure.
Billy Beane did not feel that Bartolo Colon's upcoming free agency would warrant a new extension due to Colon's rapid decline in FLUMP. Lack of femoral leverage results in a lack of dollars offered within the Sabermetrician's inner circle.
