M&M historically for the last half of the 20th century has referred to Mickey Mantle and Roger Maris;the M&M boys; the two famous sluggers on the New York Yankees of the 1950's and 60's; the double M's later became the brand of candy by the same initials.

M-16

U.S. military's proud gas operated, air cooled, light weight, hand held piece of shit. It is very sensitive to all elements that you'd find outdoors, including air and sunshine. It jams if fly shit gets into the bolt so essentially it's not much of a infantry weapon. It must be cleaned constantly to be able to fire a full magazine, and after that it needs more maintanence. To extend a grunt's life on the battlefield, the A2 variant isn't fully automatic, so there will be some time between dissasembly and cleaning. The reason it became standard issue in the U.S. military is because in the 1960's Colt executives bought some high ranking military brass a few beers and lapdances. Other than that, there's no reason why a recognized military would adopt such garbage.

PFC.Smith:"Hey Jones, i can't open this beer!"
PFC.Jones:"Use the ejection port on your M-16, stupid."

M.N.P.

stands for must not procreate.

Applied to morons who, by law, should not be allowed to make children.

Bill: so, last week, I started para sailing and I was looking up at the sky instead of the ground, so I look down and see that I'm about to land in this swamp full of alligators.

Me: wait, you para sailed over a fucking swamp?

Bill: yeah.

Me: dude you are beyond M.N.P. You're to the point now that you're too stupid to exist.
