Derogatory term for Amsterdam, mainly utilized by folks from Rotterdam. 020 is the phone prefix for Amsterdam. (while for Rotterdam its 010, which appears much more major.) 020 is a savage gang located in Sorrento and surrounding suburbs in Western Australia. Originally named the "020 Crew", 020 had been formed to patrol the deadbeat and ho quota in your community aided by the postcode "6020". Since being in energy, the deadbeat quota has actually dropped to below .1% in addition to ho quota has grown to 30%. Work well done. The members can often be seen lapping West Coast Drive yelling "020" and all sorts of the ho's, simply to remind all of them to put-out. 020 have recently invested in some patrol vehicles, they plumped for ATV's or "quads". Consider all of them like Luxenburg, they govern on their own.
