2.
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
They clearly want to eliminate our Fourth Amendment Right to protection from illegal search and seizure with their checkpoints, and lowering the legal blood alcohol will do absolutely nothing to lessen the number of drunk driving deaths

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.
MADD should be in the kitchen.

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
