M16A1mean? Here you find
The standard-issue rifle for U.S. Servicemen in Vietnam. Designed by Eugene Stoner as the Ar-15 to replace the M14 (which was difficult to control while in full-auto). The rifle fired .223 caliber ammunition, which later became the 5.56 mm NATO round in widespread use today. The M16A1 "spawned" the current U.S. service rifle, the M16A2, as well as the A3 (full-auto A2), and the M4 Carbine, which is in use by Special Forces units around the world.

The most bitched about weapon in Call of Duty 4. M16+Red Dot Sight+Stopping Power=The bane of COD4 fanboys and the main setup of losers.
The dance where you re-enact equipping the M16 on the popular video game Call Of Duty 4 Modern Warfare whilst kicking your back foot against the floor shouting BING BNG BING
getting killed or killing some one with an M16, usually playing Call of Duty 4, or another game
An individual in either Call of Duty 4: Modern Warfare or Call of Duty: Modern Warfare 2 who only uses the M16A4, in essence whoring themselves out. Typically, this weapon is used in conjunction with stopping power, capitalizing on the amount of whoreness they display. When encountered and killed, it is customary to teabag their body while saying "ja-bar-bar" in a Soulja Boy fashion.
