An online forum exclusively for members of the U.S. Democratic Party and those from the "left" side of the U.S. political spectrum. In the absence of outside conflict or critique, the forum isn't so much a place to develop political and philsophical savvy as much as simply a "hang out" spot to belittle conservatives, trumpet the successes of Democratic officials and candidates, and to serve as a social spot for like-minded people.
George W. Bush angers me! I'm going on Democratic Underground to vent and have fun.
This is an insult. The pejorative refers to an extremely stupid person who, while not actually having Down's Syndrome, has an intelligence equated to that of someone who suffers from that genetic ailment. It is usually used to attack someone who has made a grave error in speech or action, or holds beliefs or takes actions not to the insulter's liking.
Many would object to this term because of its implicit devaluing of persons with Down's Syndrome.
Goddamn it, you spilled hot coffee on my crotch, you fucking downsball!
Eddie likes Chevrolets and has been buying them for years. He's such a downsball in his taste in cars.
