M-16

The U.S. Military's standard issue assault rife, fires 5.56x45mm ammo. Developed to replace the M-14 Rifle that fired larger heavyer 7.62x51mm round. The original M-16 was first issued in Vietnam in 1965 and was prone to jamming because of the gunpowder used in the bullets, the fact that no cleaning kits were issued at first, also the soldiers using them were told it was so "space age" that it didn't need to be cleaned. It was also the first assault rifle issued en-masse to use plastic/fiberglass parts.

Soldier 1: OH SHIT VC'S ALL AROUND US!
Soldier 2: HOLD THEM OFF!
Soldier 1: WITH WHAT?!
Soldier 2: USE YOUR M-16!
Soldier 1: OH FUCK, ITS JAMMED!!!

m-o

Not an urban term at all, but a legal one. Short for Modus Operandi (method of operation). One's either habitual or premeditated way of doing things.

His m-o was always smash-and-grab

m&minize

The process of meticulously eating m&m's candy in a color-coordinated order.

Why don't you just grab a handful of m&m's and eat them? Because, I have to eat the green ones first, then the red ones, followed by the yellow ones, orange, blue, and then finally the brown ones. Why? Because I think the colors taste different, so I m&minize them!

emma m

A girl that's weird and quirky but still not bad. Sometimes shallow but not as shallow as her friends. She can be great sometimes and bad. She likes draw, game and just chill, she tries to stay shallow so no one knows her pain. (My name is Emma M)
