Well, you see, there are actually two definitions.
The first is from one of our favorite Seinfeld episodes with the infamous Bubble Boy.
The second is an acronym. See below...
(Bubble Boy's room - George pulls a Trivial Pursuit card -- The Bubble Boy's right arm ala space suit type arm and a glove at the end to protect him)
DONALD: OK, HISTORY ... THIS IS FOR THE GAME. ... HOW YA DOIN' OVER THERE? ... NOT TOO GOOD!
GEORGE: All right Bubble Boy. Let's just play... Who invaded Spain in the 8th century?
DONALD: THAT'S A JOKE. THE MOORS.
GEORGE: Oh, Noooo, I'm so sorry. It's the MOOPS. The correct answer is, The MOOPS.
DONALD: MOOPS? LET ME SEE THAT. THAT'S NOT MOOPS YOU JERK, IT'S MOORS. IT'S A MISPRINT.
GEORGE: I'm sorry the card says MOOPS.
DONALD: IT DOESN'T MATTER. IT'S MOORS. THERE'S NO, MOOPS.
GEORGE: It's MOOPS.
We have heard "Multi-objective Optimization Problem", "Material out of place", "Matter out of Place", and "Man out of Phase".
We like "Matter Out Of Place" and we feel that this pretty well represents the boys from 4055.
