M-4

HA HA M-16s aren't "Machine Guns" they are Assualt Rifles. And the M203 is not the most commonly attached equipment. That would be the M68 Sight and the PAQ-4 Infaread targeting device or the PEQ-2 Infared targeting device that EVERY member of my squad has as opposed to the 2 guys in the squad that have M-203 Grenade Launchers.

In Iraq I killed 6 Iraqis with my M-4 Carbine

"Yeah man he's M.I.A, no one has seen him in a while, he is never answering his phone and brenda said she saw him hanging out with these other people"
"thats so weird"

M*A*S*H

was a book and a movie BEFORE it was a "hit TV series." Both of these were just as entertaining, if not more so (in their own mediums).

M*A*S*H starred Donald Sutherland, Elliott Gould, Sally Kellerman, Tom Skerritt, and Robert Duvall.

M'Kay!

A phrase supplanting supercalifragilisticexpialidocious, used when one does not know what to say in reference to another person or situation, especially when one does not give a shit: As in,

Guy: "You know, if Link acquires 100 skulltulas, he will get a special reward, but it takes almost the whole game to get all of them, so what is the point, the game is over by the time you get the reward blah blah blah..."
Girlfriend: "M'kay!"

M.A.R.S.

Morning After Remorse Syndrome. The feeling of regret about the previous night's alcohol-induced activities. M.A.R.S. can have direct causes, such as engaging in buffoonery, or can be a general sense of remorse not attached to a specific incident. M.A.R.S. can exist separate from a hangover, as its effects are purely mental and emotional, rather than physical. (pronounced mahrz)

Guy A: Ah man, I have a really bad case of M.A.R.S.
Guy B: That's probably because you hooked up with that butterface and drunk-dialed your mom.
