Actually, what they mean is squatters. In many parts of Europe -especially germany and spain- it's quite normal for 16 to 25 year olds to squat abandoned buildings and live there until the police kicks them out. These kids tend to get intoxicated and do stupid stuff. Like ringing a bell in the middle of the night. The squatting thing is seen by many as a measure against speculation on living space and at the same time giving young kids a cheap place to live and get on their feet. In most places in Europe the squatting is semi-allowed because of remnants of old roman law. It's quite fascinating and -in my opinion- a tragedy that it is disappearing.
