vadding

(games)/vad'ing/ (From VAD, a permutation of ADV,i.e. ADVENT, used to avoid a particular admin's continualsearch-and-destroy sweeps for the game) A leisure-timeactivity of certain hackers involving the covert explorationof the "secret" parts of large buildings - basements, roofs,freight elevators, maintenance crawlways, steam tunnels, andthe like. A few go so far as to learn locksmithing in orderto synthesise vadding keys. The verb is "to vad" (comparephreaking; see also hack, sense 9). This term dates fromthe late 1970s, before which such activity was simply called"hacking"; the older usage is still prevalent at MIT.

Vadding (pronounced /vay'ding/) was also popular CMU, atleast as early as 1986. People who did it every night werecalled the "vaders," possibly after "elevator," which was oneof the things they played with, or "invader," or "DarthVader". This game was usually played along withno-holds-barred hide-and-seek. CMU grad students were theknown to pry open the inner doors of elevators between floorsto see the graffiti on the inside of the outer doors.

The most extreme and dangerous form of vadding is "elevatorrodeo", also known as "elevator surfing", a sport played bywrasslin' down a thousand-pound elevator car with a 3-footpiece of string, and then exploiting this mastery in variousstimulating ways (such as elevator hopping, shaft exploration,rat-racing, and the ever-popular drop experiments). Kids,don't try this at home!
