An Acronym once used to describe a band of dissidently angry wenches (aka mothers) who have never fully enjoyed the art that is drunk driving and condemn it, but in this context (the only context that matters) is used to describe the satisfying bowel movement that occurs in the morning after a night of excessive alcohol consumption.
or M.A.D.D. = Morning After Drinking Dump

Mothers Against Dudes Driving has recently attempted to pass a law prohibiting anyone from driving who isnt 70, cynial, and experiencing menopause. Who the hell are old women to tell us how to drive when they arent tall enough to see over the steering wheel. I have yet to see more than the knuckles of a MADD member when they are behind/underneath the steering wheel.

Also known as the "Mothers Against the Bill of Rights". While their cause is one which cannot be argued against, their Machiavellian tactics are unconstitutional and often pointless

The single most amazing and retardedly short person in existence. Her size has been estimated from 2-5 feet, we're not quite sure. She has many nicknames, from Madsters, to Mad Cow Disease, to Lenny. Known to use lame phrases such as 'cool beans' 'awesome sauce' and 'DAYUM'. Has a slight eyebrow twitch when irritated and is claimed to be 'vertically challenged'. Will pound you with her tiny fists or aim skilled karate chops at your face if you piss her off. She is the owner of a round, delicious badonkadonk, or ghetto bootay. Many people claim she is crazy, but really, they just can't handle her extreme level of awesomeness. Throws tic tacs back like they're goin' out of style. Her size has been estimated from 2-5 feet, we're not quite sure.
