M-4

The M-4 is a version of the M-16 machine gun with a 16" heavy barrel which has a special machined groove which is used inconjunction with the bayonet lug, to allow attachment of other devices. The most commonly attached device is a grenade launcher.
This groove is midway between the front sight and the flash-hider on the end of the barrel.

M.A.D.

abbreviation for Midwestern Ass Disease. An affliction which is rampant throughout the Midwest and particularly the Detroit area in which a girl's ass is much larger proportionately than the rest of her body. Possible causes of this disease are the cold winters, and a total lack of walking.

She looked good from the waist up, but she had a bad case of M.A.D.
