roofitti
Large-scale writings or drawings, especially on the roof of a building, done with the intent of the art being seen and photographed from space and eventually appearing on Internet resources such as Google Earth.
Some drunk Russian guys decided to write the slang for the male member on the roof of their apartment building after discovering Google Earth and called the result roofitti. See 89141.html at 3bl3bl.livejournal.com for an example.
