Guttering

[Gregory]

A prank you pull on automobiles. Involves stealing and placing off [gutters], hence the term guttering. The result is a large noise. Usually done in smaller groups (3 to 6 humans). Done in the dark usually from [11 pm] to [3 am]. Preferably earlier because sometimes cars are hard to come by really late. This is the first definition for the subject so Im assuming it is fairly unpopular.
