any gang of anarchist hobos who have banded together for the chief purpose of covertly breaking into dumpsters and living off of society's waste. often travelling on some sort of retooled vehicle run on recycled oil.
check out the dumpster pirates on their veggie bus! what an eyesore! I really hope they leave town soon.

A scavenger who will rummage through your trash cans looking for recyclables or anything of value. A trashpicker.
Those damn dumpster pirates were here again and they made a huge mess digging though the garbage in our shitcans!
