A contraction of the phrase "monkey see, monkey do." A muckadoo is often known by other names such as a liberal, a leftist, or a @#$% idiot. It is a creature that uses odd and illogical behaviors and speech patterns that it copied (sometimes with small variances) from another creature - usually another muckadoo. They are located throughout the fifty states, though are rarer in some areas while extremely common in others. They tend to infest college campuses and often can be found online at such sites as Democratic Underground and commenting at Daily Kos.
