That is the term used in this “news story” on chapelhill.indymedia.org (brought to you by the University of North Carolina at Chapel Hill’s Journalism Dept. because commercialism’s ruined reporting) to describe people who rut through dumpsters.
While you’re at the site, you can peruse recent “news” entries to read about “Our Heroic Baby-Killing Military”, indymedia’s solidarity with Palestinian terror and the new leftist anti-Semitism, plus more on their “news” fascination with the Bush/Nazi connection (here and here).
